Houston ISD (HISD) is Texas's largest school district — serving nearly 190,000 students across ~275 schools spanning central Houston, Sharpstown, Braeswood, Alief-border areas, Third Ward, Fifth Ward, and the Heights. That scale creates real diversity in how HISD families approach Credit by Examination (CBE) — from magnet-school-bound accelerators to families using CBE to smooth out gaps for students who moved into the district mid-year. This guide covers what HISD families need to know before requesting CBE.
Two related guides worth reading before you register: our district-by-district CBE deadline guide explains why there's no single statewide date, and our school start date guide explains why your district's calendar may start earlier than you'd expect — both affect how early you need to register.
This is an independent guide. Texas CBE™ is not affiliated with HISD or any Texas school district. Confirm specifics with your campus counselor.
HISD CBE testing calendar, 2026-2027
Houston ISD publishes its windows, which most Texas districts do not. These are the district's own dates, taken from the HISD Credit by Exam page and last checked on August 5, 2026. HISD notes that testing window dates are subject to change.
| Assessment | Parent request you do this | Campus submission your CTC does this | Test window | Who it is for |
|---|---|---|---|---|
| CBE #1 | Jul 6 – 10, 2026 | Jul 6 – 17 | Jul 30 – Aug 5, 2026 | K–8 skip a grade · 6–12 advance in a course |
| CBE #2 | Oct 12 – 16, 2026 | Oct 12 – 23 | Nov 9 – 13, 2026 | Grades 9–12 only · advance in a course |
| CBE #3 | Jan 18 – 22, 2027 | Jan 18 – 29 | Feb 8 – 12, 2027 | Grades 9–12 only · advance in a course |
| CBE #4 | May 10 – 14, 2027 | May 10 – 21 | Jun 7 – 11, 2027 | K–8 skip a grade · 6–12 advance in a course |
The parent request window is five days
This is the part to put in your calendar. Round Rock gives families a month. Northside gives a month. HISD gives you five days — and it is the parent request, not the campus submission, that has the short deadline. Your CTC gets one to two weeks after you, but they cannot submit a request you never made.
Miss it and the wait is not a few days. The gap between CBE #2 and CBE #3 is roughly three months; between #4 and the next #1, four.
Two of the four windows are high school only
CBE #2 and #3 are grades 9–12. If your student is in middle school and the goal is to skip a grade, only CBE #1 (July) and CBE #4 (June) are open to them — two chances a year, both in summer. A 6th–8th grader advancing in a single course can use any window; a 5th grader can only test in #1 and #4, and only for the Dual Language Immersion program.
HISD's CBE — two purposes, one program
HISD's Student Assessment department describes CBE as a test that K-12 students can take to:
- Skip a class — acceleration (no prior instruction).
- Advance faster in a course — course credit (with or without prior instruction, depending on the specific test).
HISD's key rules families need to know
| Aspect | Details |
|---|---|
| Grades 1-5 acceleration bar | 80% or higher on EACH of Language Arts, Math, Science, Social Studies for the grade level the student wants to skip |
| Course credit limit per administration | 3 courses maximum per testing administration |
| Attempts per subject | Maximum 2 attempts in the same course/subject during HISD enrollment |
| Testing calendar | Set by HISD Student Assessment department; check the official HISD CBE page |
| Registration | Through the campus counselor |
The HISD-specific rule most families miss
The 3-credit-per-administration limit and the 2-attempts-per-subject-total limit are HISD-specific constraints not found in every Texas district. Planning implications:
- A student wanting to accelerate in multiple subjects must stagger tests across administrations (can't take Algebra 1, Geometry, and Biology CBE all in one window if that would exceed 3 credits earned).
- If a student attempts Algebra 1 CBE at 7th grade and fails, they have only one attempt left for that subject across their entire HISD enrollment. Preparation matters.
How HISD families typically use CBE
- Algebra 1 acceleration before 9th grade. Strong 7th- or 8th-grader tests out to enter their zoned HS or magnet at Geometry.
- Grade-level advancement in K-5. High-ability students test out of a full grade level via the 80%-on-4-subjects rule.
- Foreign-language CBE for heritage speakers. HISD's Vietnamese, Spanish, Mandarin, and Arabic-speaking communities use CBE for language credit.
- Schedule clearing for HCC dual-credit. Earning social-studies or foreign-language via CBE clears room for Houston Community College dual-enrollment in 11th-12th grade.
- Credit gap-filling for transfer students. Families moving into HISD mid-year sometimes use CBE to establish Texas TEKS-specific credit for a course completed elsewhere.
HISD's magnet and career pathway HS options
HISD's HS landscape is more complex than most Texas districts — including comprehensive HS (Bellaire, Lamar, Milby, Sam Houston, others), magnet HS (Carnegie Vanguard, DeBakey Health Professions, HSPVA), and specialized career pathway programs. If your student is targeting a magnet application, ask specifically how a CBE credit factors into the magnet admissions review — some magnets have specific course-sequencing expectations that a CBE can satisfy.
Credit by Examination asks for 80% with no prior instruction. Full-length mock exams written to the same TEKS the exam is drawn from — Algebra 1, Geometry, Biology, Chemistry and more.

The cost case — CBE prep vs tutoring
| Path | Typical cost | What you get |
|---|---|---|
| Private subject tutor (6 weeks × 5 hr/wk) | ~$1,500–$4,500 | Personalized, expensive |
| Group prep program (Kumon-style) | ~$600–$1,200 | Slower pace, less CBE-format-specific |
| Texas CBE™ — 3-month access, one subject | $29.99 | Full-length timed mocks, TEKS-tagged, AI explanations |
With HISD's 2-attempt cap, spending on quality prep before either attempt matters more than in some other districts.
What Texas CBE™ offers HISD families
- TEKS-aligned practice questions with full-length timed mocks.
- 5-language platform — English, Korean, Spanish, Vietnamese, Chinese.
- Free sample questions, no signup.
- Full-course access $29.99 per subject for 3 months.
Three things to verify with your HISD counselor
- Attempt history for the target subject. The 2-per-subject limit is total across enrollment — check what's already been used.
- Whether the target testing administration would exceed 3 course credits. If your student is accelerating in multiple subjects, plan the sequence.
- Placement effect if the student passes. HISD's diverse HS landscape means placement rules differ by campus — magnet-track students should get magnet admissions counselor sign-off separately.
The realistic timeline for fall 2026-2027 acceleration
- Late spring: Contact your campus counselor. Get the current HISD testing administration calendar.
- Take a free practice exam to confirm fit — HISD's 2-attempt cap makes this pre-check important.
- Register early for the target administration through the counselor. Confirm attempt count against the 2-per-subject cap.
- Test. Ensure your student is well-prepared — burning an attempt without prep is costly given the cap.
- Result processing: ~2-6 weeks typical.
- Placement: Applied to the fall schedule if results arrive in time and magnet admissions (if applicable) sign off.
Counselor email — copy and adapt
Subject: Credit by Exam request — [Your child's name], [grade] grade
Hi [Counselor's name],
I'm [your name], parent of [child's name] in [grade] at [school]. I'd like to request information about HISD's Credit by Exam for [subject or grade-level advancement].
Specifically:
- My student's CBE attempt count for this subject (I want to confirm we haven't hit the 2-per-subject limit).
- The next CBE administration date and application deadline.
- The 3-course-credit-per-administration limit — I want to plan the sequence if my student is accelerating in multiple subjects.
- For grades 1-5: confirmation of the 80%-on-4-subjects rule (Language Arts, Math, Science, Social Studies).
- Any magnet-specific placement rules if my student is on a magnet track.
Could we set up a 15-minute meeting?
Thank you,
[Your name] · [phone] · [child's school ID]
How to start today — 4 steps
- Take a free practice exam (5 minutes). Pick a subject. HISD's 2-attempt cap makes this important — don't skip.
- Upgrade to full-length timed mocks ($29.99 / 3 months / subject) if prep is needed.
- Email your HISD counselor using the script above. Confirm attempt count first.
- Register for the target administration. Plan around the 3-credit-per-admin ceiling if accelerating in multiple subjects.
