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 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.

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

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

1. Algebra 1 acceleration before 9th grade. Strong 7th- or 8th-grader tests out to enter their zoned HS or magnet at Geometry.
2. Grade-level advancement in K-5. High-ability students test out of a full grade level via the 80%-on-4-subjects rule.
3. Foreign-language CBE for heritage speakers. HISD's Vietnamese, Spanish, Mandarin, and Arabic-speaking communities use CBE for language credit.
4. 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.
5. 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 $29.99 per subject for 6 months.

Three things to verify with your HISD counselor

1. Attempt history for the target subject. The 2-per-subject limit is total across enrollment — check what's already been used.
2. Whether the target testing administration would exceed 3 course credits. If your student is accelerating in multiple subjects, plan the sequence.
3. 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.
