Poem: Code for a better future

Some see code—just ones and zeros— but in young minds, it shapes tomorrow’s heroes. A world is born, a dream takes flight, with every loop, with every byte.

So learn with heart, and build with care— the future's written everywhere: in lines of code, in sparks that glow, in every lesson, watch it grow.

Best resources that match the new AP CSA syllabus

College Board AP CSA CED + AP Classroom — essential

Use these as the master specification for everything else. The new four units are:

Unit 1 — Using Objects and Methods: 15–25%

Unit 2 — Selection and Iteration: 25–35%

Unit 3 — Class Creation: 10–18%

Unit 4 — Data Collections: 30–40%. (AP Central)

Also download the Course at a Glance, Java Quick Reference, sample FRQs, scoring guidelines, and use the AP Classroom question bank/progress checks. The current exam is fully digital in Bluebook, with 42 MCQs / 90 minutes / 55% and 4 FRQs / 90 minutes / 45%. (AP Central)

CSAwesome2 — my #1 free recommendation

This is probably the best match for your situation if you want a complete teaching resource without buying a commercial package. CSAwesome2 was specifically rewritten for the 2025–26 AP CSA revision and is College Board endorsed. (Runestone Academy)

Its structure follows the new framework:

Using Objects and Methods → Selection and Iteration → Class Creation → Data Collections, with interactive Java coding, exercises, quizzes, lesson plans, FRQ practice and practice exams. (Runestone Academy)

Important: use CSAwesome2, not the old CSAwesome v1 / “AP CSA Java Course 2019–2025.” (Runestone Academy)

CodeHS AP CSA — Cortado

If you want a polished LMS-style course with lots of automatically graded coding exercises, AP Computer Science A (Cortado) is the correct new version. CodeHS states that Cortado is its most up-to-date AP CSA course, and College Board recognizes it as an endorsed curriculum. (CodeHS)

Particularly useful are its Java practice problems, Question of the Day, AP CSA review course, digital textbook, FRQ Center, labs and supplemental projects. (CodeHS)

Be careful: CodeHS Nitro and Mocha are explicitly marked as the old 2019 AP CSA framework. Do not build a new 2026–27 course around those versions. (CodeHS)

NJCTL AP Computer Science A — excellent free teacher materials

College Board lists NJCTL as an endorsed provider. Its resources include presentations, guided programming activities, classwork/homework, labs, quizzes, tests, AP exam preparation, unit plans and an approved AP syllabus. The materials are also editable. (AP Central)

This is especially useful if you prefer a traditional teacher presentation → examples → classwork → homework → assessment structure rather than having students spend the whole lesson inside an online course.

Code.org AP Computer Science A

College Board also endorses Code.org's CSA curriculum. It now offers both an objects-first approach and a version arranged according to the sequence of the new AP CSA CED. (AP Central)

I would consider it particularly useful for students who are relatively new to programming and need more scaffolding.

CompuScholar Java Programming

CompuScholar has updated and re-endorsed its Java Programming curriculum specifically for the Fall 2025+ CED. It includes lessons, videos, quizzes, tests, coding exercises, projects, an approved syllabus and an AP exam topic cross-reference. (CompuScholar)

The major advantage is teacher workload: many exercises and projects are automatically graded. (CompuScholar)

Barron's AP Computer Science A Premium, 13th Edition

If you want a printed exam-preparation book, make sure you get the 13th Edition / 2026 edition, not an older Barron's copy. The publisher description specifically states that this edition incorporates the revised CED and College Board changes for 2025–26. (亚马逊)

What I would use for your AP CSA classes

For a teacher building a course from scratch, I would not buy a large curriculum immediately. I would build the course around:

College Board CED + AP Classroom → official specification and exam questions

CSAwesome2 → main student textbook/course

CodeHS Cortado → extra coding practice and FRQ practice

NJCTL → PowerPoints, classwork, homework and assessments

Bluebook practice → digital exam preparation. (AP Central)

That combination can cover almost everything you need.

One particularly important change for lesson planning is the FRQ structure. Students should be trained repeatedly on exactly these four forms: Methods & Control Structures, Class Design, Data Analysis with ArrayList, and 2D Array. (AP Central)

If you are preparing materials for the 2026–27 school year / May 2027 exam, the Fall 2025 CED shown in your image remains the current framework; College Board currently lists no newer AP CSA framework change. (AP Central)
