Houston ISD CBE — Parent Guide: 80% Grade 1-5, Max 3 Credits/Admin, 2 Attempts/Subject (2026-2027)
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.

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.
Subjects most commonly pursued
- Algebra 1, Algebra 2, Geometry, Pre-Calculus — acceleration pipeline.
- Spanish I/II, Vietnamese, Mandarin — heritage-speaker CBE.
- U.S. History, World Geography, World History — social-studies acceleration.
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 $19.99 per subject for 6 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.
