Contents of the Mathematics Placement Test
Since 1978, UW system faculty and Wisconsin high school teachers have been collaborating to develop a test for placing incoming students into college Mathematics courses. The current test includes four components: elementary algebra, intermediate algebra, college algebra, and trigonometry. These components are available for each UW System campus to use according to its individual needs and resources. Each campus determines the appropriate scores for entry into specific courses. The purpose of this brochure is to introduce you to the test, describe the rationale behind its creation, and outline future plans for its continued development.
Background and Purpose of the Test
In 1978, following the publication of the UW System Basic Skills Task Force Report, members of Mathematics Department Faculties from UW System institutions met in Madison to discuss common entry-level curriculum problems. One problem most departments shared was how to effectively place incoming freshmen into an appropriate mathematics course. Placement procedures and tests varied from campus to campus and it seemed that some consistency was desirable. The decision was made to develop a System-wide test for placement into an introductory mathematics curriculum.
The committee that would begin this task would consist of representatives from any UW System Mathematics Department that chose to participate. The departments would select their representatives and participation would be strictly voluntary.
The first step in the project was to carefully analyze each of the individual curricula in the System and write a detailed set of prerequisite objectives for all courses prior to calculus. After this list was approved by all campuses, the committee began developing test items on the skills identified in their test objectives. Through a series of pilot administrations at area high schools and UW campuses, the committee obtained valuable information about how the individual items performed, and gained important insights into item writing strategies and techniques. Many items were refined or corrected, as necessary, and repiloted in an effort to improve their ability to distinguish between students with different levels of mathematical preparedness. After a sufficient number of high quality items had been developed, they were assembled into a complete test. The first operational form of the Mathematics Placement Test was administered in 1984.
Placement into college courses is the sole purpose of this test. The experienced teacher will quickly realize that many skills which are taught in the high school mathematics courses are not included in the test. This was by design, as the test is a tool to assist advisors in placing students into the best course in the university-level mathematics sequence. The questions on the test were specifically selected with this single purpose in mind. This means the test is not a measure of everything that is learned in high school Mathematics courses. The test was not designed to measure program success or to compare students from one high school with students from another. It should be viewed only as a tool to be used for placing students at the university level.
As a placement instrument, the test has to be easy enough to identify those students needing remedial help, yet it also has to be complex enough to identify those students who are ready for calculus. Scores have to be precise enough to allow placement into many different levels of university coursework. In addition, the test has to be efficient to score, since thousands of students each year need to have their results promptly reported. In order to meet these criteria, the test development committee selected a multiple-choice format. The items measure four different areas of mathematical competence: elementary algebra, intermediate algebra, college algebra, and trigonometry. Each skill area has a different set of detailed objectives, carefully developed to best match university mathematics curricula across the University of Wisconsin System.
Every year, a new form of the Mathematics Placement Test is published, along with some new pilot items for each component of the test, and administered to all incoming Freshmen in the UW System. All items are subjected to a statistical review to identify which items effectively distinguish the students with the strongest mathematics skills or the weakest mathematics skills from the general population of students. Only the items which are most useful for differentiating among students are ever considered for use on a future form of the test.
Although faculty cannot be considered disinterested observers, those who are familiar with the placement test feel that its quality is extremely high. The feeling among faculty at the participating UW institutions is that the test has helped enormously in placing students into appropriate courses. One of the strengths of the Mathematics Placement Test is that it is developed by faculty from throughout the University of Wisconsin System. Therefore, this test represents a UW System perspective with respect to the underlying skills that are necessary for success in our courses. One of the challenges, in this regard, is that the UW System campuses do not have a single Mathematics curriculum. Instead, each campus has its own curriculum and its own courses, which may or may not correspond well with courses on other UW campuses. To ensure that the placement test works well on each UW campus, each UW institution determines its own cutscores so as to optimize placement into its own Mathematics course sequence. Consequently, cutscores will vary from campus to campus as a result of curricular differences and student population differences. Also, on many campuses, the placement test is but one of several variables used for placing students, often also including ACT/SAT score, units of high school mathematics, and grades in high school mathematics courses.
The ability of this test to appropriately place students into courses rests in the quality of the match between test content and the institutional curricula at each UW campus. To ensure that the test mirrors the curriculum in introductory mathematics courses throughout UW System, the Mathematics Placement Test Development Committee has expanded to include one representative from most of the 14 UW institutions, as well as one Wisconsin high school mathematics teacher. This committee generally convenes twice each year to write and revise test items and discuss issues pertaining to test content and university curricula.
Over the past few years, the Mathematics Placement Test has changed in several very important ways. Prior to the fall of 2000, the different campuses were combining items in different ways to form placement scores and make placement decisions. The particular set of items used by any one campus was selected to best match that campus’ introductory curriculum. However, because campuses combined the test items in different ways, students who transferred from one UW institution to another often found themselves without valid placement scores and needing to retake the test. In 2000, the Mathematics Placement Test Development Committee agreed upon a common method for combining test objectives to create a uniform set of scores for reporting performance on the placement test. The three agreed-upon scores, one corresponding to each new objective, are labeled mathematics basics, algebra, and trigonometry. These three scores are now used by all System institutions.
Historically, the Mathematics Placement Test has always been organized in three different sections, labeled A, B, and C. Students were instructed to take either sections A and B (which contained elementary and intermediate algebra) or sections B and C (which contained intermediate and college algebra and trigonometry), depending upon their mathematics background and desired college placement. However, our experience was that many students found it difficult to accurately assess their level of preparedness and would often take the wrong two sections. On most campuses, students who scored too high on the AB test or too low on the BC test could not be placed accurately and were required to retest with the appropriate two sections of the test. This was very inconvenient, both for the students and for the university’s testing office. Beginning in the fall of 2002, the three different sections were shortened and combined, and all students were asked to complete the entire test. This has helped eliminate the confusion over which two sections to take and has reduced the number of students needing to retest.
General Characteristics of the Test
1. All items are to be completed by all students. The items are roughly ordered from elementary to advanced. The expectation is that less prepared students will answer fewer questions correctly than more prepared students.
2. The test consists entirely of multiple choice questions, each with five choices.
3. The test is scored as the number of correct answers, with no penalty for guessing. Each item has only one acceptable answer. This number correct score is converted to a standard score between 150 and 850 for the purposes of score reporting.
4. The Mathematics Placement Test is designed as a test of skill and not speed. Ample time is allowed for most students to answer all questions. Ninety (90) minutes are allowed to complete the test.
5. The mathematics basics component has a reliability of .85. The algebra component has a reliability of .90. The trigonometry component has a reliability of .85. For all three sections, items are selected of appropriate difficulty to provide useful information within the range of scores used for placement throughout the System campuses.
The Mathematics Test Development Committee decided on three broad categories of items: mathematics basics, algebra, and trigonometry. The entire Mathematics Placement Test is designed to be completed in 90 minutes, sufficient time for most students to complete the test.
Items for each of the three components are selected to conform to a carefully created set of detailed objectives. The percentage of items selected from each component are shown in Table 1 below.

Additional Statements About High School Preparation for College Mathematics Study
The number of high schools offering some version of calculus has increased markedly since the UW System Math Test Committee's first statement of objectives and philosophy, and experience with these courses has shown the validity of the Committee's original position. This position was that a high school calculus program may work either to the advantage or to the disadvantage of students depending on the nature of the students and the program. Today, it seems necessary to mention the negative possibilities first.
A high school calculus program not designed to generate college calculus credit is likely to mathematically disadvantage students who go on to college. This is true for all such students whose college program entails use of mathematics skills, and particularly true of students whose college program involves calculus. High school programs of this type tend to be associated with curtailed or superficial preparation at the precalculus level and their students tend to have algebra deficiencies which hamper them not only in mathematics courses but in other courses in which mathematics is used.
The positive side is that a well-conceived high school calculus course which generates college calculus credit for its successful students will provide a mathematical advantage to students who go on to college. A study by the Mathematical Association of America identified the following features of successful high school calculus programs:
1. they are open only to interested students who have completed the standard four year college preparatory sequence. A choice of mathematics options is available to students who have completed this sequence at the start of their senior year.
2. they are full year courses taught at the college level in terms of text, syllabus, depth and rigor.
3. their instructors have had good mathematical preparation (e.g. at least one semester of junior/senior level real analysis) and are provided with additional preparation time.
4. instructors expect that their successful graduates will not repeat the course in college, but will get college credit for it.
A variety of special arrangements exist whereby successful graduates of a high school calculus course may obtain credit at one or another college. A generally accepted method is for the students to take the Advanced Placement Examinations of the College Board. Success rates of students on this exam can be a good tool for evaluation of the success of a high school calculus course.
The range of objectives in this document represents a small portion of the objectives of the traditional high school geometry course. The algebra objectives represent a substantial portion of the objectives of traditional high school algebra courses. The imbalance of test objectives can be explained in part by the nature of the entry level mathematics courses available at most colleges. The first college mathematics course generally will be either calculus or some level of algebra. A choice is usually based on three factors: (1) high school background; (2) placement test results; (3) curricular objectives. One reason for the emphasis on algebra in this document and on the test is that virtually all college placement decisions involve placement into a course which is more algebraic than geometric in character.
Still, there are reasons for maintaining a geometry course as an essential component in a college preparatory program. Since there are no entry level courses in geometry at the college level, it is essential that students master geometry objectives while in high school. High school geometry contributes to a level of mathematical maturity which is important for success in college.
Students should have the ability to use logic within a mathematical context, rather than the ability to do symbolic logic. The elements of logic which are particularly important include:
1. Use of the connectives "and’ and "or" plus the "negation" of resultant statements, and recognition of the attendant relationship with the set operations "intersection," "union," and "complementation."
2. Interpretation of conditional statements of the form "if P then Q," including the recognition of converse and contrapositive.
3. Recognition that a general statement cannot be established by checking specific instances (unless the domain is finite), but that a general statement can be disproved by finding a single counter example. This should not discourage students from trying specific instances of a general statement to conjecture about its truth value.
Moreover, logical thinking or logical reasoning as a method should permeate the entire curriculum. In this sense, logic cannot be restricted to a single topic or emphasized only in proof-based courses. Logical reasoning should be explicitly taught and practiced in the context of all topics. From this, students should learn that forgotten formulas can be recovered by reasoning from basic principles, and that unfamiliar or complex problems can be solved in a similar way.
Although only two of the objectives explicitly refer to logic, the importance of logical thinking as a curriculum goal is not diminished. This goal, as well as other broad-based goals, is to be pursued despite the fact that it is not readily measured on placement tests.
Problem solving involves the definition and analysis of a problem together with the selecting and combining of mathematical ideas leading to a solution. Ideally, a complete set of problem solving skills would appear in the list of objectives. The fact that only a few problem solving objectives appear in the list does not diminish the importance of problem solving in the high school curriculum. The limitations of the multiple choice format preclude the testing of higher level problem solving skills.
MATHEMATICS ACROSS THE CURRICULUM
Mathematics is a basic skill of equal importance with reading, writing, and speaking. If basic skills are to be considered important and mastered by students, they must be encouraged and reinforced throughout the curriculum. Support for mathematics in other subject areas should include:
– a positive attitude toward mathematics
– attention to correct reasoning and the principles of logic
– use of quantitative skills
– application of mathematics curriculum.
COMPUTERS IN THE CURRICULUM
The impact of the computer on daily life is apparent, and consequently many high schools have instituted courses dealing with computer skills. While the learning of computer skills is important, computer courses should not be construed as replacements for mathematics courses.
There are occasions in college math courses when calculators are useful or even necessary (for example, to find values of trig functions), so students should be able to use calculators at a level consistent with the level at which they are studying mathematics (four-function calculators initially, scientific calculators in pre-calculus). A more compelling reason for being able to use calculators is that they will be needed in other courses involving applications of mathematics. The ability to use a calculator is very definitely a part of college preparation.
On the other hand, students need to be able to rapidly supply from their heads – whether by calculation or from memory – basic arithmetic, in order to be able to follow mathematical explanations. They should also know the conventional priority of arithmetic operations and be able to deal with grouping symbols in their heads. For example, students should know that (-3)2 s is 9, that -32 is -9, and that (-3)3 is -27 without needing to push buttons on their calculators. Moreover, students should be able to do enough mental estimation to check whether the results obtained via calculator are approximately correct.
Beginning in the spring of 1991, the use of scientific calculators has been allowed on the UW Mathematics Placement Test. The test was redesigned to accommodate the use of scientific calculators, so as to minimize the effects on placement due to the use or nonuse of calculators. Exact numbers such as π, continue to appear in both questions and answers where appropriate.
Use of scientific, non-graphing calculators is optional. Each student is advised to use or not use a calculator in a manner consistent with his or her prior classroom experience. Calculators will not be supplied at the test sites.
Mathematics curricula and faculty throughout UW are divided on whether or not to permit graphing calculators in classrooms. There remain many college-level courses for which graphing calculators are not allowed. Therefore, the placement test has not been revised to accommodate the use of graphing calculators. Students may not use graphing calculators for the Mathematics Placement Test.
PROBABILITY AND STATISTICS
Although university curricula are somewhat in a state of flux, with many basic issues and philosophies being examined, the normal entry level courses in mathematics remain the traditional algebra and calculus courses. Therefore, the placement tests must reflect those skills which are necessary for success in these courses. This is not intended to imply that courses stressing topics other than algebra and geometry are not vital to the high school mathematics curriculum, but rather that those topics do not assist in placing students in the traditional university entry level courses.
Probability and statistics are topics of value in the mathematical training of young people today that are not reflected on the placement test. It is the Committee's feeling that these topics are important to the elementary and secondary curriculum. They are gaining significance on university campuses, both within mathematics departments and within those departments not normally thought of as being quantitative in nature. The social sciences are seeking mathematical models to apply, and in general these models tend to be probabilistic or statistical. As a result, the curriculum in these areas is becoming heavily permeated with probability and statistics.
Mathematics departments are finding many of their graduates going into jobs utilizing computer science or statistics. Consequently, their curricula are beginning to reflect these trends. The Committee urges the educational community to develop and maintain meaningful instruction in probability and statistics.
How Teachers Can Help Students Prepare for the Test
The best way to prepare students for the placement tests is to offer a solid mathematics curriculum and to encourage students to take four years of college preparatory mathematics. We do not advise any special test preparation, as we have found that students who are prepared specifically for this test, either by practice sessions or the use of supplementary materials, score artificially high. Often such students are placed into a higher level course than their background dictates, resulting in these students either failing or being forced to drop the course. Due to enrollment difficulties on many campuses, students are unable to transfer into a more appropriate course after the semester has begun.
Significant factors in the placement level of a student are the high school courses taken as well as whether or not mathematics was taken in the senior year. Data indicate that four years of college preparatory mathematics in high school not only raises the entry level mathematics course, but predicts success in other areas as well, including the ability to graduate from college in four years.
Teachers should certainly feel free to encourage students to be well-rested and try to remain as relaxed as possible during the test. We intend that the experience be an enjoyable, yet challenging one. Remember that the test is designed to measure students at many different levels of mathematical preparedness; all students are not expected to answer all items correctly. There is no penalty for guessing, and intelligent guessing will most likely help students achieve a higher score.
Use of the Tests
When the UW System Mathematics Placement Tests were developed, they were written to be used strictly as a tool to aid in the most appropriate placement of students. They were not designed to compare students, to evaluate high schools or to dictate curriculum. The way an institution chooses to use the test to place students is a decision made by each institution. The Center for Placement Testing can and does help institutions with these decisions.
Each campus will continue to analyze and modify its curriculum and hence will continue to modify the way in which it uses the placement tests to place students. Cutoff scores might need to be changed over time to reflect the prerequisites for a campus’ curriculum. It is also important for follow-up studies to be made to determine the effectiveness of the placement procedures. Contact must be maintained with the high schools so that modifications in the curriculum in both the high schools and in the UW System can be discussed.
