Which of the following statements about kindergarten attendance is true?

The statement that kindergarten attendance is optional and becomes mandatory at 1st grade in some states is correct. In the United States, kindergarten is not universally mandated across all states, meaning that families have the choice to enroll their children or not. However, in several states, attendance becomes compulsory starting at the 1st grade, which means that while children can begin their formal education in kindergarten, they aren’t legally required to attend until they reach the following grade level.

This option accurately reflects the variability in educational laws across different states regarding the age at which formal education becomes compulsory. Many states allow parents the flexibility to decide when their child is ready to enter kindergarten, recognizing that children develop at different rates.
