Katy ISD Credit by Exam — Parent Guide: 80% Accelerate, 4 Windows, First-Day Rule (2026-2027)
Katy ISD (KISD) sits in west Houston and is one of Texas's largest and fastest-growing districts — serving Katy, Fulshear, and portions of west Houston. With eight comprehensive high schools plus specialized options (Miller Career and Technology Center, Raines Academy, and others), KISD serves a highly diverse acceleration-minded family base. This guide covers what KISD families actually need to know before requesting Credit by Examination for acceleration.

Katy ISD CBE testing calendar, 2026-2027
Katy ISD publishes its calendar, which most Texas districts do not. These are the district's own dates, from the KISD Credit by Examination page and its 2026-2027 calendar PDF, last checked on August 5, 2026. The calendar covers grades 1–12.
| Testing window | Location | Parent application deadline you do this | Campus ordering deadline |
|---|---|---|---|
| Nov 16 – 20, 2026 | Home campus | Oct 9, 2026 | Oct 16, 2026 |
| Mar 1 – 5, 2027 | Home campus | Feb 5, 2027 | Feb 10, 2027 |
| Jun 7 – 10, 2027 | TBD | Apr 16, 2027 | Apr 23, 2027 |
| Jul 12 – 15, 2027 | TBD | May 8, 2027 | May 12, 2027 |
Apply about five weeks before you test
Katy runs long lead times: 38 days between the parent application deadline and the November window, and 65 days for the July one. That is generous compared with Houston ISD, which gives parents a five-day request window and tests three weeks later — but it cuts the other way too. The paperwork is due long before the test feels close, and by the time a family starts thinking about a November exam in late October, the door has already shut.
There is no early-autumn window
The 2026-2027 calendar opens in November. A family hoping to place a student before the school year settles has no window to use — the first opportunity of the year is the one closing October 9, and the exam itself is in mid-November. Plan around that rather than around the start of school.
Katy ISD's CBE program at a glance
KISD's Research, Assessment, and Accountability office offers CBE at every grade level and subject area offered, in accordance with Texas State Board of Education rules. The two pass thresholds are the standard state-set values:
| Path | Prior instruction? | Passing bar |
|---|---|---|
| Acceleration (no prior instruction) | No | 80% or above |
| Credit recovery (prior instruction) | Yes | 70% or above |
KISD's key rules (unique-ish among Houston-area districts)
- Advance one grade level OR one course per subject per academic year. A student cannot double-jump within a subject in the same year.
- Four CBE testing windows per year, with NO exceptions to ordering deadlines. KISD is strict — miss the deadline, wait for the next window.
- For acceleration to count: results must be received by the first day of school. This is the rule that surprises most families. A summer CBE window that runs late (missed deadlines, scoring delays) can push the acceleration to the next school year, not the current one.
- K-8 acceleration is by grade level; 9-12 is by subject/course (high-school credit only).
- Applications through the campus counselor.
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.

- Algebra 1 acceleration before 9th grade. Strong 7th- or 8th-grader tests out in the summer CBE window to enter their zoned HS (Katy HS, Seven Lakes, Tompkins, Cinco Ranch, Taylor, Morton Ranch, Mayde Creek, or Paetow) at Geometry.
- Foreign-language CBE for heritage speakers. KISD's diverse Indian-heritage, Vietnamese, Chinese, Korean, and Spanish-speaking families use CBE to convert home languages into transcript credit.
- Geometry the summer between 9th and 10th. Second-stage acceleration for math-track students.
- Schedule clearing for HCC dual-credit. Earning social-studies via CBE clears room for Houston Community College dual-enrollment in 11th-12th grade.
Subjects most commonly pursued
- Algebra 1, Algebra 2, Geometry, Pre-Calculus — the acceleration pipeline.
- Spanish I/II, Vietnamese, Chinese — heritage-speaker CBE.
- U.S. History, World Geography, World History — social-studies acceleration.

Three things to verify with your KISD counselor
- The current testing window's ordering deadline. KISD applies no exceptions — a missed deadline pushes to the next window (up to a full semester later).
- Whether the results will arrive by the first day of school for a summer CBE targeting fall acceleration. If not, plan for the following year.
- Acceleration limit for the year. One grade level or one course per subject per year — verify which counts against the limit if your student has already tested.
