The full 2026 distribution

The published 3-or-higher figure (63%) is quoted verbatim rather than summed from the bands above. The College Board rounds each band independently, so the two can differ by a point; the published figure is the correct one.

What this actually tells you

The most common outcome on CS Principles was a 3, earned by 30% of students. 63% reached a 3, which is 9.9 points below the 72.9% average across the 35 exams with published 2026 figures.

A 5 goes to roughly one student in 10, which makes it a genuinely demanding target on this exam. Plan the review phase around timed practice rather than rereading notes.

37% of students scored a 1 or a 2 — a large share, and the single most useful number on this page. A third of the cohort not reaching a 3 is a signal about pacing and exam technique as much as content.

One caveat worth holding onto: cut scores are reset every year, so a distribution describes a past cohort rather than predicting yours. Use it to calibrate expectations, not to estimate your own score — the score calculator does that from your actual raw points.

Common questions

What percent of students get a 5 on AP Computer Science Principles?

10% of students earned a 5 on AP Computer Science Principles in 2026. That ranks 33rd out of the 35 AP exams with published 2026 distributions, against an average of 18.9% across those exams.

What is a good score on AP Computer Science Principles?

A 3 is the College Board's "qualified" threshold and 63% of students reached it. Whether that is good enough depends entirely on your target colleges: some grant credit at a 3, many require a 4, and competitive programs often require a 5. Look up each school's published AP credit policy rather than relying on a general rule.

Is AP Computer Science Principles one of the harder AP exams?

By outcome, CS Principles sits 33rd of 35 for percent scoring 3 or higher — 9.9 points below the average AP exam. Read that carefully though: a distribution reflects who takes the exam as much as how hard it is. Courses with small, self-selected cohorts score high without being easy.

What is the average score on AP Computer Science Principles?

The mean is 2.9 out of 5, which ranks 35th of 35. The most common single outcome was a 3, earned by 30% of students. The College Board publishes the percentage in each band but not the mean; 2.9 is the weighted average of those five published percentages.
