McKinney ISD (MISD) is a Collin County district serving over 24,000 students across three comprehensive high schools — **McKinney High School**, **McKinney Boyd High School**, and **McKinney North High School** — plus Serenity High School (alternative campus). Unlike Allen's single-HS model or Frisco's decentralized 10-HS system, MISD's three-HS structure means each campus has its own counseling team but shares the district's Advanced Academics and Assessment office for CBE administration.

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 McKinney ISD or any Texas school district. Confirm specifics with your campus counselor.

## McKinney ISD's CBE — the essentials

| Aspect | MISD rule |
| --- | --- |
| **Program** | Credit by Examination — administered by the District Assessments office |
| **Two purposes** | (1) **Acceleration** — earn credit for a course "without prior instruction". (2) **Credit recovery** — earn credit "with prior instruction" on a previously attempted course. |
| **Passing bar (acceleration)** | **80%** per Texas Education Code §28.023 |
| **Passing bar (credit recovery)** | **70%** per 19 TAC §74.24 |
| **Application** | Through the **campus counselor** at your student's school; approval from Academic Advisement / Advanced Academics office |
| **Testing window** | Set by the District Assessments office — confirm the 2026-2027 window with your campus counselor |
| **High school campuses** | McKinney HS, McKinney Boyd HS, McKinney North HS, Serenity HS |

## The three McKinney high schools — what to know

- **McKinney High School** — the original comprehensive HS ("the Lions"), central campus. Full IB and AP program.
- **McKinney Boyd High School** — western attendance zone ("the Broncos"), newer campus with a large advanced-academics enrollment.
- **McKinney North High School** — northern attendance zone ("the Bulldogs").
- **Serenity High School** — alternative campus.

All three comprehensive HS follow the same district CBE policy, but the counselor teams and testing logistics are campus-specific. Ask your campus counselor first.

## How MISD families typically use CBE

1. **Algebra 1 acceleration between 8th and 9th grade.** Middle-schoolers who've mastered pre-algebra content take Algebra 1 CBE the summer before 9th grade to enter high school at Geometry.
2. **Geometry acceleration between 9th and 10th grade.** Sets up Algebra 2 in 10th, Pre-Calc in 11th, and AP Calculus BC in 12th.
3. **Foreign-language CBE.** Heritage speakers (Spanish, Korean, Chinese, Vietnamese, Hindi) formalize their existing fluency into transcript credit.
4. **Clearing schedule for Collin College dual-credit.** MISD partners heavily with Collin College — CBE-earned credit in electives creates room for dual-credit in 11th and 12th grade.
5. **Credit recovery.** Recovering a course previously attempted follows the 70% credit-recovery bar.

## Subjects most commonly pursued

- **Algebra 1, Algebra 2, Geometry, Pre-Calculus** — the acceleration pipeline toward AP Calc.
- **Spanish I/II, Korean, Chinese, Hindi** — heritage-speaker CBE.
- **World Geography, World History, U.S. History** — social-studies acceleration.
- **Biology** — to reach AP Bio or AP Chem earlier.

## What Texas CBE™ offers McKinney ISD families

- TEKS-aligned practice with full-length timed mocks (built around the 80% acceleration bar).
- **5-language platform** — English, Korean, Spanish, Vietnamese, Chinese — a fit for MISD's diverse student population.
- Free sample questions, no signup required.
- Full-course access $29.99 per subject for 3 months.

## Three things to verify with your MISD counselor

1. **Whether it's acceleration (80%) or credit recovery (70%).** The passing threshold depends on which purpose applies.
2. **Current 2026-2027 testing window.** MISD's District Assessments office publishes dates; the campus counselor has the schedule.
3. **Placement effect.** Passing CBE grants the credit, but placement into the next-level course at MISD is confirmed by the counselor before testing.
