MARYLAND - The College Board says the Maryland class of 2013 led the nation in high scoring on Advanced Placement tests.
The New York-based organization said in a report Tuesday that 29.1 percent of last year's Maryland public high school graduates scored a 3 or higher on an AP exam. That compares with a national rate of 20.1 percent.
A score of 3 or higher is considered a successful test result.
The report says Maryland also made progress toward eliminating the gap in AP program participation between white and black students, the most underrepresented group in AP classrooms.
In AP programs, college faculty members work with secondary school teachers to help students demonstrate that they are ready for the challenge of higher education.
