McKinney ISD CBE — Parent Guide: 80%/70% Passing, 3-HS Structure (2026-2027)

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.

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

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

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.
