In most states, children must be 5 years old by August or September to enter kindergarten that academic year. However, in Texas, a child must be at least five years of age on September 1 of the school year to be eligible to attend a kindergarten program. It is important to note that kindergarten attendance is not required in most states, and compulsory school attendance starts at age 6 or later in 42 states.
To summarize, the age at which kindergarten starts varies by state, but in Texas, a child must be at least five years old on September 1 of the school year to attend kindergarten.
