We need to:
Get more information about what happens to students who study calculus in high school.
Establish and enforce guidelines for high school programs offering calculus.
Re-examine first-year college mathematics.

High school calculus should be pushing more students toward the study of higher mathematics in college.
It appears to be having exactly the opposite effect.

Number 1 complaint from high school teachers:
The focus of college placement tests is on what my students don’t know, rather than on what they know.
Colleges need to pay more attention to building on what students understand and can do.

2001–06 study at Arizona State University
Of students who took pre-calculus and • Their declared major required at least one semester of calculus, and • They earned an A in pre-calculus,
43% chose not to enroll in calculus.
![Page 21: AP Calculus and the Transition to College Mathematicsbressoud/talks/2010/T3-transition.pdf · AP® Calculus and the Transition to College Mathematics David Bressoud Macalester College,](https://reader030.vdocument.in/reader030/viewer/2022040409/5ec1a04d9b1f607e205dca7e/html5/thumbnails/21.jpg)
During the period fall 2001 through fall 2006,
43% of engineering majors, 54% of mathematics majors,
51% of physical science majors, and 50% of technology majors
who enrolled in Calculus I at ASU and whose intended majors required Calculus II never earned credit for Calculus II.
