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](https://www.texascbe.com/blog/texas-cbe-deadlines-district-by-district-guide) explains why there's no single statewide date, and our [school start date guide](https://www.texascbe.com/blog/texas-school-start-dates-doi-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](https://www.houstonisd.org/schools-academics/academics/student-assessment-2/cbe) 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

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.

The request window is five days. Knowing where your student stands takes one afternoon.

HISD requires **80%** to award credit. A free sample tells you whether that is within reach before you ask your CTC to file — and before the window closes for three months.

## 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.

## 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

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.

Next HISD parent request window: October 12–16, 2026.

That one is grades 9–12. If your student is in middle school and aiming to skip a grade, the next window open to them is CBE #4 in May. Either way, the useful thing to do today is find out how close they already are to 80%.

Full access is $29.99 per subject for three months.

## The realistic timeline for fall 2026-2027 acceleration

1. **Late spring:** Contact your campus counselor. Get the current HISD testing administration calendar.
2. **Take a free practice exam** to confirm fit — HISD's 2-attempt cap makes this pre-check important.
3. **Register early** for the target administration through the counselor. Confirm attempt count against the 2-per-subject cap.
4. **Test.** Ensure your student is well-prepared — burning an attempt without prep is costly given the cap.
5. **Result processing:** ~2-6 weeks typical.
6. **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:

1. My student's CBE attempt count for this subject (I want to confirm we haven't hit the 2-per-subject limit).
2. The next CBE administration date and application deadline.
3. The 3-course-credit-per-administration limit — I want to plan the sequence if my student is accelerating in multiple subjects.
4. For grades 1-5: confirmation of the 80%-on-4-subjects rule (Language Arts, Math, Science, Social Studies).
5. 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

1. **Take a free practice exam (5 minutes).** [Pick a subject](https://www.texascbe.com/subjects). HISD's 2-attempt cap makes this important — don't skip.
2. **Upgrade to full-length timed mocks** ($29.99 / 3 months / subject) if prep is needed.
3. **Email your HISD counselor** using the script above. Confirm attempt count first.
4. **Register for the target administration.** Plan around the 3-credit-per-admin ceiling if accelerating in multiple subjects.
