Academic redshirting is the choice to hold a kindergarten-eligible child out of school for an extra year, usually when a birthday falls close to the state cutoff. Whether it’s a good idea depends on your child, and whether it’s even allowed depends on where you live. In roughly 20 states and Washington, D.C., kindergarten attendance is legally required once your child hits the eligible age, which closes the door on redshirting without a specific exemption. In the other 30 or so states, compulsory attendance doesn’t start until age six, seven, or in a few cases eight, which leaves a legal window to wait a year with no paperwork at all. The research on whether that extra year actually helps is less flattering than most parents expect.
Is Redshirting Legal in Your State
Every state sets a date by which a child must turn five to start kindergarten that year. The most common cutoff is September 1, used by about 20 states, with others ranging from July 31 in states like Hawaii and Kentucky to as late as January 1 in Connecticut.1National Center for Education Statistics. State Education Reforms – Kindergarten Entry Age Requirements If your child’s birthday falls after your state’s cutoff, they aren’t eligible yet, and waiting isn’t redshirting; it’s just the calendar. Redshirting only describes the choice to wait when your child is already old enough to enroll.
The question that actually matters legally is when your state requires attendance to begin. Those are two separate ages, and the gap between them is where redshirting lives.
States Where Kindergarten Is Mandatory
In roughly 20 states and the District of Columbia, kindergarten attendance is legally required. Compulsory attendance begins at age five, which means once your child reaches the eligible age by the cutoff date, you are generally required to enroll. States in this group include Arkansas, Connecticut, Delaware, Hawaii, Louisiana, Maryland, New Mexico, Oklahoma, Rhode Island, South Carolina, South Dakota, Virginia, and Washington, D.C., among others.1National Center for Education Statistics. State Education Reforms – Kindergarten Entry Age Requirements
Some of these states offer narrow exceptions. Louisiana, for example, allows children to pass a readiness screening in place of attending kindergarten before entering first grade. These are not blanket permissions to skip a year. If you live in a mandatory-kindergarten state and want to delay, read your state’s specific exemption rules closely, because simply not enrolling can trigger truancy or educational neglect concerns.
States With a Legal Window to Wait
In the other 30 or so states, compulsory school attendance doesn’t begin until age six, seven, or in a few cases eight. That gap between kindergarten eligibility at five and the compulsory age is what makes redshirting legally straightforward in those states.2Education Commission of the States. 50-State Comparison: Free and Compulsory School Age Requirements If your state doesn’t require attendance until six, you can keep your five-year-old home or in preschool for another year without notifying the district or filing any paperwork.
The most common compulsory age is six, which applies in states including California, Alabama, Florida, Georgia, Illinois, and Michigan. In practical terms, if your state’s cutoff is September 1 and compulsory attendance starts at six, a child born in August can sit out kindergarten at five and enroll the following year at six with no formal process. You enroll when you’re ready, as long as it’s before the compulsory age kicks in. Once your child reaches that age, they must be in a public school, a private school, or an approved homeschool program.
Districts That Are Closing the Loophole
A growing number of districts are eliminating redshirting by requiring that children who turn six before the school year starts enroll in first grade instead of kindergarten. If your child skips kindergarten entirely when they finally show up, there’s no reason to hold them out in the first place.
A large Georgia district recently announced that any child who is six by the start of the 2026–27 school year will be placed in first grade. Washington, D.C. public schools have begun enforcing a similar rule in the other direction, requiring children who turn five by September 30 to enter kindergarten that year. These policies are still the exception, but they’re worth confirming with your district before you commit to a plan built around delaying a year.
What the Research Says About the Benefit
Parents usually redshirt hoping to give their child a lasting academic or social edge. The evidence doesn’t really support that hope. Redshirted children do tend to start kindergarten ahead of their younger classmates, which makes sense because they’ve had an extra year of development. But the advantage fades. By third grade, redshirted children score about the same as peers who entered on time.3NWEA. New NWEA Analysis Examines Trends in Kindergarten Redshirting
The pattern across studies is consistent: short-term gain, long-term wash. That doesn’t rule out redshirting for a specific child with specific developmental concerns. It does mean the general assumption that older-in-the-class produces better outcomes doesn’t hold up.
The Cost of the Extra Year
Redshirting is only free if a parent or caregiver is already home full-time. For everyone else, it means another year of preschool or childcare tuition. National estimates for center-based preschool for a four- or five-year-old run roughly $10,000 to $14,000 per year on average, with large variation by location. Urban areas and coastal states tend to run significantly higher.
Given that the academic boost fades by third grade, you’re paying for a temporary advantage. That doesn’t mean cost should drive the decision alone, but it should be part of the math. For some families, the same money will do more good spent on tutoring, enrichment, or saved for later educational costs.
If Your Child Has or May Have a Disability
Delaying kindergarten creates complications most parents don’t anticipate when a disability is in the picture. Federal law requires school districts to identify and evaluate all children with disabilities in their boundaries, enrolled or not, under what’s known as the “child find” obligation.4Individuals with Disabilities Education Act. 34 CFR 300.111 – Child Find So your child can still be evaluated and receive early intervention during a redshirting year.
The problem shows up on the other end. Federal law requires states to provide a free appropriate public education to children with disabilities between the ages of 3 and 21.5Individuals with Disabilities Education Act. 20 USC 1412 – State Eligibility That cap doesn’t move. Delaying school entry by a year means your child still ages out of special education services on the same birthday, so you’ve effectively traded a year of transition support in their late teens or early twenties for a year of preschool at five.
The outcomes data isn’t reassuring either. One study found that redshirted children were more than twice as likely to receive special education services by third grade compared to children who started on time. The extra year did not appear to reduce the eventual need for services. One exception stood out: children with speech-language impairments showed higher reading and math scores when redshirted than peers with the same impairment who entered on time.6MDPI.

High School Athletic Eligibility
This is the consequence nobody considers when a child is four. Most state high school athletic associations set an age limit, typically 19, beyond which a student cannot compete. The exact rule varies: some states disqualify a student who turns 19 before a specific date in the school year, others use different dates in the athletic calendar. A redshirted student will be a year older than classmates throughout school, which makes hitting that ceiling before senior season more likely.
Students with fall or winter birthdays usually clear it, because they’ll still be 18 for most of senior year. Students with spring or summer birthdays who were redshirted could turn 19 during their final season. If serious high school athletics are a realistic possibility, check your state athletic association’s age rules before committing to the delay.
Making the Call for Your Child
Three questions do most of the work. First, is it legal where you live, and does your district still allow a redshirted child to enter kindergarten rather than first grade? Second, can you absorb another year of preschool or childcare costs without strain? Third, do you have a specific reason connected to your particular child, rather than a general sense that older is better? The research suggests the general assumption doesn’t pay off, but a specific concern grounded in how your child is developing is a different conversation.
If you redshirt in a state where kindergarten isn’t mandatory, there’s generally no record to reconcile and no deferral to file. You simply register during the normal enrollment window the following year. If you filed any kind of waiver or deferral, keep the paperwork. Most families never need it, but a paper trail costs nothing and heads off questions later.
