STAAR Texas EOC Prep with TEKS-Aligned Practice: How Our Algebra 1, Biology, and US History Question Banks Cover Both STAAR and Texas Credit by Examination
If your child is preparing for the STAAR (State of Texas Assessments of Academic Readiness) end-of-course (EOC) exams, here's an important fact most Texas families miss: the STAAR EOC and the Texas Credit by Examination (CBE) test the same content — the Texas Essential Knowledge and Skills (TEKS) curriculum standards. Same standard, same content. Different exam, different purpose.
Because our practice exams are TEKS-tagged, the same $19.99 Algebra 1 purchase that prepares a student for the CBE also prepares them for the STAAR Algebra I EOC. One purchase, two test-prep purposes. Below we explain how the overlap works, what each STAAR EOC tests, and where to find the official TEA calendar.
The STAAR EOC subjects
The Texas STAAR EOC exams currently include the following five subjects (per the Texas Education Agency Student Assessment Division):
| STAAR EOC Subject | Underlying TEKS standard | Our matching practice |
|---|---|---|
| Algebra I | TEKS §111.39 | Algebra 1 practice — same TEKS |
| English I | TEKS §110.36 | Not currently in our subject lineup |
| English II | TEKS §110.37 | Not currently in our subject lineup |
| Biology | TEKS §112.34 | Biology practice — same TEKS |
| U.S. History | TEKS §113.41 | U.S. History practice — same TEKS |
Three of the five STAAR EOC subjects map directly to our existing practice products: Algebra I, Biology, and U.S. History. Our Geometry and Algebra 2 practice exams cover the TEKS content for those courses; while neither is currently a STAAR EOC subject, the practice prepares students for the broader Texas math sequence including AP Precalculus and SAT Math.
Why TEKS-aligned practice works for both STAAR and CBE
This is the key insight Texas families often miss:
- STAAR EOC — administered by the Texas Education Agency (TEA), tests TEKS, results count for state accountability and (formerly) graduation. Each spring + summer + fall administration.
- Texas Credit by Examination (CBE) — administered by school districts or UT High School (UTHS), tests TEKS, results grant high-school course credit (80% TEC §28.023 acceleration, 70% 19 TAC §74.24 prior-instruction).
Different administrators, different uses, same underlying TEKS content. A student who masters TEKS §111.39 for Algebra 1 has prepared for both the STAAR Algebra I EOC and the CBE Algebra 1 exam.
Our practice exams are TEKS-tagged at the question level. Every question maps to a specific TEKS sub-standard (e.g., a question testing solving systems of linear equations is tagged to TEKS §111.39(c)(5)(C)). This is the same standard that STAAR uses to construct the EOC exam.
Where to find the official STAAR test dates
The TEA Student Assessment Division publishes the annual Texas Assessment Operating Manual with the official testing windows. Test dates change every year, so we won't list specific dates here — check the official source:
📅 Official STAAR test dates
- Texas Education Agency Student Assessment Division: tea.texas.gov/student-assessment
- Texas Assessment Operating Manual (annual document with the official testing calendar)
- Texas Assessment Resources for Educators and Families — the parent-facing TEA page
The general pattern: spring main administration in early-to-mid May (Algebra I, English I, English II, Biology, US History EOC, plus grades 3–8 STAAR); summer retesting in late June; fall retesting in early December. Your school district publishes the exact local administration dates within these statewide windows.
How to use our practice for STAAR prep
Same approach as CBE prep:
- Take the free 20-question sample in Algebra 1 (or Biology, or US History — whichever STAAR EOC your child needs). No signup. Score is your starting point.
- If 85%+ cold, your child is tracking well for that STAAR EOC. A few timed mocks before test day to lock in stamina.
- If 70–85%, real prep needed. Upgrade to $19.99 / 6 months / subject. Use mocks 2× per week for 4–6 weeks. AI explanations on every wrong answer identify exactly which TEKS sub-standards need work.
- If under 70%, concept-level gaps. Start with our Concept Lessons (free, no signup) for the underlying topics — the STAAR EOC will be a struggle until those foundations click.
What we are NOT
To be clear about the relationship:
- We are NOT the STAAR exam. The TEA administers the STAAR, we don't.
- We do NOT have access to actual STAAR questions. Our questions are independently authored to test the same TEKS standards.
- We do NOT predict STAAR pass rates. Your child's actual STAAR performance depends on many factors beyond practice scores.
- We are NOT affiliated with TEA, the STAAR program, the College Board, or any school district.
What we offer: independently authored, TEKS-tagged practice exams that prepare students for the same content STAAR EOC tests. Honest content overlap, not exclusivity claims.
What about the grades 3–8 STAAR (not EOC)?
The grades 3–8 STAAR exams (Reading, Math, Science, Social Studies) test grade-level TEKS for those grades. Our subject catalog currently focuses on high-school subjects (Algebra 1, Geometry, Algebra 2, Pre-Calculus, Biology, Chemistry, US History, SAT Math), so the grades 3–8 STAAR is not the primary fit for our practice. If you're preparing a 5th- or 8th-grader for the grade-level STAAR Math, consider age-appropriate prep first; our Algebra 1 content becomes useful once your student starts pre-algebra in 6th–7th grade.
Recommended next steps
- Identify which STAAR EOC your child takes this year. Algebra I and English I are the freshman year exams. Biology is typically 10th grade. US History is typically 11th grade. English II is 10th grade.
- Take the matching free practice in our system to gauge readiness.
- If the score gap is real, $19.99 / 6 months gives you full-length timed mocks for the subject. Practice the way the actual exam tests — timed, no shortcuts.
- Use our Concept Lessons for the underlying TEKS topics where the practice exposes gaps.
- Confirm the actual STAAR administration date with your school. Each district publishes its own local administration date within the TEA statewide window.

This article is for general information only and is not legal or educational advice. STAAR exam content, dates, scoring rules, and accommodations are set by the Texas Education Agency (TEA) and individual school districts and they change year to year — always confirm with your school counselor and the TEA Student Assessment Division before relying on any specific date or policy. The Texas Credit by Examination (CBE) is a separate program with its own statutory framework (TEC §28.023, 19 TAC §74.24). Texas CBE is an independent practice platform; it is not affiliated with, endorsed by, or operated by the Texas Education Agency, the STAAR program, Pearson Education (which administers parts of the STAAR program), UT High School, Texas Tech University ISD, the College Board, or any school district, and it does not administer the STAAR exam, the Texas CBE, or any official exam, nor does it grant Texas academic credit. Our practice exams are independently authored TEKS-aligned questions designed to test the same standards as the official Texas assessments; they are not actual STAAR or CBE questions.
