More than 13,000 Cobb County students took the new Preliminary SAT, scoring better than state and national averages on the standardized test.

The PSAT exam administered by the College Board tests 10th- and 11th-graders in math, reading and writing. It's a warm-up for the SAT, which colleges use to help determine whether to admit a student. The latest results are for students who took the exam in October 2015.

The test was redesigned by the College Board to align the PSAT with the new SAT exam that will be given for the first time in March.

More than 6,800 Cobb 10th-graders or 80 percent of the 10th grade took the PSAT. The average total score for Cobb 10th-graders was 965. Cobb’s total score exceeds the state average by 64 points and the national average by 33 points, according to a statement from the school district.

Cobb’s average reading and writing score was 487 compared with the state average of 452 and national average of 468. Cobb’s average math score was 477 compared with the state average of 448 and the national average of 464.

About 6,200 students, 47 percent of Cobb 11th-graders, took the PSAT. Students received an average total score of 1113, exceeding the state and national averages of 1018 and 1009.

Some 11th-grade students take the PSAT to participate in the National Merit Scholarship program, which provides over 8,000 students nationwide with scholarships worth a total of more than $43 million.

Walton High School had the highest total score in the district, 1124. Lassiter’s total score of 1064 was second highest in the district. Three other schools, Kennesaw Mountain, Pope, and Wheeler, also had total scores higher than 1000.
