What Happens When an Elementary Class Exceeds 22 Students?
Texas class-size rules, state exceptions, family notice, and the staffing questions behind the number.
Quick answer
Texas generally limits prekindergarten through fourth-grade classes to 22 students. When a covered classroom exceeds that limit, a district must follow the state exception process and related notice requirements.
What changed or what the rule says
An exception is not a permanent removal of the rule. It is a defined state process tied to a particular staffing circumstance and reporting period.
Why this matters to Katy ISD
Class size affects workload, individual attention, intervention capacity, classroom management, and district staffing choices.
What I would watch as a trustee
I would examine which campuses and grades repeatedly need exceptions, why they occur, how families are notified, and what staffing response is realistic.
What this does not mean
The 22-student limit does not apply identically to every grade, course, or instructional setting.
