The Texas Algebra 1 Credit by Exam (CBE): A Complete Guide to Testing Out and Accelerating (2026)
Of all the subjects Texas students test out of, Algebra 1 is the most common — and for good reason. Algebra 1 is the first rung on the high-school math ladder, and earning the credit early through Credit by Exam (CBE) can reshape a student's entire four-year math path. This guide explains how the Algebra 1 CBE works, what it tests, and how to prepare for it effectively.
Why Algebra 1 is the #1 acceleration subject
The standard Texas math sequence is a ladder: Algebra 1 → Geometry → Algebra 2 → Pre-Calculus → Calculus. Every rung depends on the one below it, so the earlier a student climbs onto the ladder, the higher they can reach by senior year. A motivated student who earns Algebra 1 credit by exam before 9th grade can enter high school at Geometry — which opens the door to reaching AP Calculus by senior year without doubling up on math courses or giving up electives.
Because Algebra 1 sits at the very bottom of the ladder, it is the single highest-leverage subject for acceleration. Testing out here doesn't just earn one credit; it shifts the timing of every math course that follows.
Exam format
The Algebra 1 CBE is administered as a standardized exam. Based on the general CBE format used across Texas subjects:
| Feature | Detail |
|---|---|
| Format | Multiple-choice, online, proctored (Proctorio at home) |
| Time limit | 3 hours (180 minutes) |
| Questions | Typically around 50 multiple-choice questions (verify current specs with UT High School) |
| Passing — acceleration | 80% for credit by exam without prior instruction (Texas law) |
| Passing — recovery | 70% for credit by exam with prior instruction |
| Calculator / formula sheet | Varies by subject — verify with UTHS |
Note the two passing thresholds. If your student is accelerating (testing out of a course they never formally took), the bar is 80%. If they're using CBE for credit recovery after prior instruction, the bar is 70%. Question counts vary by exam, so always confirm the current specifications with UT High School (UTHS) or your campus counselor before registering.
What's tested: the Algebra 1 §111.39 TEKS
The Algebra 1 CBE is built on the Texas Essential Knowledge and Skills (TEKS) for Algebra 1, found in state standard §111.39. The course splits into two semesters:
| Semester A | Semester B |
|---|---|
|
|
Semester A is anchored in linear thinking — slope, intercepts, writing and solving equations and inequalities, and reading data. Semester B moves into nonlinear functions — quadratics, exponentials, and polynomial operations. Both semesters share the algebraic-methods skills (notation, sequences, literal equations).
The topics students most often underestimate
Plenty of students arrive confident from the linear material and then stumble in Semester B. Three areas tend to be underestimated:
- Quadratic functions and equations. Quadratics can be solved several ways — factoring, completing the square, the quadratic formula, and graphing. Students who learned only one method often freeze when a problem is set up for a different one. Comfort with all the solution methods, and knowing when each is fastest, is what separates a confident score from a shaky one.
- Exponential functions. After a full semester of straight-line thinking, exponential growth and decay feel genuinely different. Recognizing exponential behavior in a table, graph, or word problem — and distinguishing it from linear — is a frequent trip-up.
- Polynomial factoring patterns. Difference of squares, perfect-square trinomials, and grouping are pattern-recognition skills. They're not hard once you see the pattern, but they need rehearsal so the pattern jumps out under time pressure.
A simple prep approach: diagnose → focus → confirm
- Diagnose. Start with a full-length practice exam under realistic conditions to see where you actually stand across the §111.39 categories — not where you assume you stand.
- Focus. Spend your study time on the lowest-scoring categories rather than re-grinding what you already know. For most students that means weighting Semester B (quadratics, exponentials, polynomials) more heavily.
- Confirm. Re-test with another full-length mock under timed conditions to confirm your weak categories have come up before exam day.
This loop is more effective than open-ended review because it puts your hours where they move the score.
How Texas CBE™ helps
Texas CBE™ is built to support exactly this approach for Algebra 1:
- TEKS-aligned practice questions that mirror the §111.39 topics and the multiple-choice format.
- Full-length mock exams modeled after the official CBE format — same style and length, so practice resembles test-day conditions.
- Per-TEKS-category scoring so you can see exactly which Algebra 1 categories need work, with step-by-step explanations and smart question rotation.
- Free sample questions on Algebra 1 — no signup required.
- A 5-language platform (English, Korean, Spanish, Vietnamese, Chinese) for families who prefer to review explanations in another language.
Full-course Algebra 1 access is $29.99 for 6 months, currently offered at an automatic launch discount of 20% (effective $23.99) — typically less than a single CBE retake fee.
