NAMPA, Idaho (AP) — Math curriculum are getting changes in parts of the state as schools look to better prepare teenagers for first-year college courses.

The Idaho Press-Tribune reports average SAT scores in math and reading and writing were slightly better than the rest of the country, but students in southwestern Idaho struggled.

The Caldwell school district had 16 percent and Nampa school district had 24 percent of students scoring high enough to qualify as college ready last year.

Both are using test data to improve math curriculum.

Students need SAT scores of at least 510 in math and 480 on reading and writing to reach the College Board's benchmark for college readiness.

Those students have a 75 percent chance of earning no less than C's in those freshman-level classes.
