A few states (like California and Texas) use an August 31st cutoff. If your child\u2019s birthday falls after the cutoff, they will start kindergarten the following year.<\/p>\n\n\n\n<p>Many families also choose “redshirting”\u2014delaying kindergarten by one year\u2014especially for children with summer birthdays. This gives them extra time to develop social, emotional, and academic skills before starting school.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-old-are-you-in-elementary-middle-and-high-school\"><\/span>How Old Are You in Elementary, Middle, and High School?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>US K-12 education is divided into three main levels, each with a standard age range.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Elementary School Age USA (K\u20135)<\/h3>\n\n\n\n<p>Parents often ask questions like \u201chow old are you in 5th grade usa\u201d or \u201cwhat grade is a 10 year old in.\u201d In most US schools, elementary students are between 5 and 11 years old.
