What does 22-1 mean? 

According to sources at the Texas Education Agency, no teacher in grades PK-4 can have more than 22 children in attendance.  For several years, TEA allowed districts to have an overflow class where one class per grade level was able to grow up to 24.  That provision has been ended, and any PK-4 class over 22 is a violation of state law.  A district can obtain a waiver from this provision if it can prove that it cannot find a teacher to teach a new class or that there is no space available for another class.  If a  waiver is granted, it is valid for only one semester.  Teachers who have more than 22 students in their rooms should contact their association.
