One of the most common questions parents ask is: \u201cWhen should my child start school?\u201d The answer depends on your child\u2019s birth date and your state or country\u2019s cutoff date for kindergarten enrollment. Some children just make the cutoff, while others may need to wait nearly a full year. Use our free School Age Calculator<\/a> to determine exactly when your child is eligible for kindergarten and each subsequent grade.<\/p>\n\n\n\n

How Kindergarten Cutoff Dates Work<\/h2>\n\n\n\n

In the United States, kindergarten eligibility is determined by state law, and most states require a child to be 5 years old by a specific cutoff date. Common cutoff dates include:<\/p>\n\n\n\n

\n
Cutoff Date<\/th>Example States<\/th>What It Means<\/th><\/tr><\/thead>
September 1<\/td>California, Connecticut, Michigan<\/td>Child must turn 5 on or before Sep 1 to start kindergarten that fall<\/td><\/tr>\n
August 31<\/td>Texas, Ohio, Missouri<\/td>Child must be 5 by Aug 31 for the current school year<\/td><\/tr>\n
October 1<\/td>New York (varies by district), Virginia<\/td>Later cutoff means more children qualify each year<\/td><\/tr>\n
December 1<\/td>Some districts in New Jersey, Pennsylvania<\/td>Late cutoff \u2014 children can start as young as 4<\/td><\/tr>\n
January 1<\/td>Connecticut (varies)<\/td>Very late cutoff \u2014 some children start kindergarten at age 4<\/td><\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n

Cutoff dates are determined at the state or district level, and some states allow local districts to set their own. For a personalized result, use the School Age Calculator<\/a> with your child\u2019s birth date and your state.<\/p>\n\n\n\n

Grade-by-Grade Age Requirements<\/h2>\n\n\n\n
