#### Determine Student Placement in a Precalculus or Calculus Course

Use this 33-question placement test to identify which course, precalculus or calculus, is more suitable for students. The test questions were designed by two veteran faculty members at Texas A&M University with experience teaching both precalculus and calculus. Their goal was “to develop a reliable, robust measure of the preparedness of incoming students for college-level calculus.”

Texas A&M University has the second largest engineering program in the United States, with over 8,000 undergraduate engineering majors. This test is required for all incoming students who plan to take Calculus for Engineers and has been extensively reviewed.

##### Test Details

**Randomized Questions.** Each question has several versions of the same difficulty, so each student gets a different exam of identical difficulty.

**Statistics-Based Placement.** Based on Texas A&M statistical analysis and student population:

- Students with a score of 28 or higher have a 90% likelihood of passing Calculus I.
- Students with a score of 22 or higher have a 70% likelihood of passing Calculus I.
- If a student scores below 22, it’s recommended he or she enroll in a precalculus course or take a remediation course.

**Insightful Analytics.** Analysis tools in PlaceU can help determine the appropriate cut-off scores for your specific institution.

**Competitive Pricing.** Available through PlaceU for $12 per student per test.

##### Test Efficacy

Faculty members at Texas A&M University conducted a statistical analysis of the test scores as well as statistical analyses of grade outcome and retention results over the past five years. A statistical measure of reliability (Cronbach’s α) was found to be 0.90 or higher. This was true both cumulatively and by year. This indicates the high internal consistency of the placement test both longitudinally and cumulatively and places it in the same range as high-stakes tests such as the SAT and GRE. This statistic was calculated from more than 15,000 exams. In general, good internal consistency among items on a test is indicated when the Cronbach’s α coefficient is greater than 0.8.

Additionally, if the relationship between grades in Calculus I and test scores is expressed as the probability of passing Calculus I given a score range, the result is an accurate prediction regarding the success (retention rate) of how students typically perform in Calculus I.
