Harford County Public Schools achieved an all-time high in student participation in Advanced Placement testing this year, the district announced Tuesday.

Advanced Placement testing is standardized testing that assesses student mastery of college-level material learned in AP courses offered as electives in county high schools.

In 2024, about 3,964 students participated in AP testing. This year, that number grew to a record 5,423.

The pass rate for this year’s testing, 64%, exceeded last year’s, which was 61.6. The district record of 65.3 was set in 2006.

Harford County Public Schools Superintendent Sean Bulson said this year’s participation and performance reflect the students’ determination and the strength of the district’s instructional program and commitment to academic excellence.

“What’s particularly impressive is that as the number of tests taken increased, overall scores rose as well,” he wrote in a statement.
