Dallas ISD (DISD) is the second-largest school district in Texas — serving over 140,000 students across 200+ campuses. Dallas ISD's CBE program has its own acronym: **CEFA — Credit by Examination for Acceleration**, administered by the Assessment Department alongside separate Credit by Examination (CBE) for other purposes.

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 DISD. Confirm specifics with your campus counselor.

## Dallas ISD's CEFA — the essentials

| Aspect | DISD rule |
| --- | --- |
| **Program name** | **CEFA — Credit by Examination for Acceleration** (distinct from CBE for credit recovery) |
| **Passing bar (MS/HS)** | **80% mastery** to receive course credit for middle-school and high-school students |
| **Passing bar (elementary grade acceleration)** | **80% mastery or higher in all four subjects**: language arts, mathematics, science, social studies |
| **Credit recovery bar** | 70% for CBE (credit recovery, with prior instruction) per 19 TAC §74.24 |
| **Administration** | DISD Assessment Department; registration through campus counselor |
| **DISD Assessment Website** | assessment.dallasisd.org — CBE/CEFA materials and manuals |

## CEFA vs CBE — Dallas's distinction

Dallas ISD is one of the districts that explicitly separates the two purposes with two program names:

- **CEFA** — Credit by Examination for Acceleration. For a course the student has **not had prior instruction** in. Passing = 80% mastery.
- **CBE** — Credit by Examination. For credit recovery on a course the student has had prior instruction in. Passing = 70% mastery.

This distinction matters when registering — using the wrong term with the counselor can lead to the wrong test being administered.

## The elementary all-four-subjects rule

Like Northside ISD in San Antonio, Dallas ISD requires **80% mastery in all four subjects** for elementary students who want to accelerate an entire grade level. Missing 80% in one of language arts, math, science, or social studies blocks the acceleration even if the other three are perfect.

## How Dallas ISD families typically use CEFA/CBE

1. **Algebra 1 CEFA between 8th and 9th grade.**
2. **Elementary grade skip** — with the 80% × 4-subject requirement.
3. **Foreign-language CEFA** — Spanish, Vietnamese, Chinese, Korean-heritage speakers.
4. **Magnet-school prep** — CEFA-earned advanced placement helps in magnet-application course profiles (School of the Talented and Gifted / Booker T. Washington / etc.).
5. **CBE for credit recovery** on a course previously attempted (70% bar).

## What Texas CBE™ offers Dallas ISD families

- TEKS-aligned practice with full-length timed mocks (80% CEFA bar).
- 5-language platform — English, Korean, Spanish, Vietnamese, Chinese (fit for DISD's diverse population).

## Three things to verify with your DISD counselor

1. **Confirm whether it's CEFA (80% acceleration) or CBE (70% credit recovery)** — the correct program name matters at registration.
2. **Elementary families: prepare all four subjects**, not just the strongest one.
3. **Current 2026-2027 testing window and registration deadline.**
