The Narrowing — Nine Point Five

AP Computer Science in high school

2,246 Black students took AP Computer Science A in 2020. 715 of them were girls.

Depends on your school

Congratulations on getting curious about computer science. Your track starts with two courses your school may already offer.

There are two AP Computer Science courses. AP Computer Science Principles teaches you the foundations of the field. AP Computer Science A is where you begin writing real programs.

Take Principles first. What you learn there is what you will use in the second course to do the actual programming.

In 2020, Black students were 6.9% of AP Computer Science Principles exam takers and 3.5% of AP Computer Science A takers, against roughly 15% of American K-12 enrolment. In absolute terms: 2,246 Black students took AP Computer Science A in the entire country, and 715 of them were girls. This is a number you could fit in a high school gymnasium.

The College Board's own data says what to do about it. Black students who take AP Computer Science Principles are about three times more likely to go on to AP Computer Science A, and more than three times more likely to major in computer science. For 68% of Black students in the class of 2019 who took it, AP Computer Science Principles was their first AP STEM course of any kind.

That is the single most actionable finding in this campaign. The broad course is not a consolation prize for the real one — it is the thing that produces the real one. A school deciding which AP to add should know that.

This route only exists where the course is offered and actually runs. 80% of Black students attend a school that offers computer science, which is the good news; enrolment is where the number falls.
