IDEA Part B governs special education services for students in which age range?

• A. Ages three through twenty-two.
• B. Birth through age three.
• C. All ages from birth to twenty-five.
• D. Only adults.

Answer: (A)

IDEA Part B provides special education and related services to eligible students who have disabilities from ages 3 through 21. This age range is set so that school-age children receive tailored supports in the public education system, with the IEP in effect through the end of the school year in which the student turns 21 or graduates with a regular high school diploma, whichever comes first. Infants and toddlers from birth to age 2 receive services under IDEA Part C (early intervention), which is separate from Part B. The other options don’t fit because birth through 3 falls under Part C, and extending beyond 21 goes beyond the standard Part B age range.
