100% sure my daughter is ready for the test, should I hold her back a year? Her birthday is Dec. 5.
This is a question many parents ask, especially when their child’s birthday falls close to the school district’s cutoff date. If your daughter was born on December 5, she may be one of the youngest children in her grade, and it is natural to wonder whether waiting an extra year might improve her readiness for school or admissions testing.
The answer largely depends on whether you are considering a public or private school.
Public Schools
In most public school districts, parents generally cannot delay enrollment simply to give a child more time to mature or improve test performance. School districts establish age-based eligibility rules, and children are expected to enroll according to those guidelines.
For example, many districts have a specific cutoff date that determines kindergarten eligibility. Once a child reaches the required age, they are expected to enter school with their age group. If parents choose to delay enrollment beyond the allowable timeframe, the child may be placed in first grade rather than kindergarten because they have aged out of kindergarten eligibility.
Since enrollment policies vary by district and state, it is important to check your local school district’s current kindergarten entrance requirements.
Private Schools
Private schools often have more flexibility in admissions decisions. Some schools may allow families to delay kindergarten entry if they believe an additional year would benefit the child socially, emotionally, physically, or academically.
This practice is commonly known as “redshirting.” Redshirting occurs when parents intentionally delay a child’s school entry to give the child more time to mature before beginning kindergarten.
Families sometimes consider redshirting when a child:
- Has a late birthday and would be among the youngest students in the class
- Needs additional social or emotional development
- Struggles with attention, confidence, or self-regulation
- Is physically smaller than peers
- Would benefit from another year of preschool or pre-kindergarten
However, redshirting is not always the right choice. Some children with late birthdays are academically, socially, and emotionally ready to thrive with their age group.
Should You Delay Testing?
Many parents worry that their child is not “100% ready” for a gifted test, admissions assessment, or school interview. The reality is that very few parents ever feel completely certain.
Rather than waiting for the perfect moment, focus on helping your child build confidence through everyday learning experiences, reading together, conversations, play-based learning, and gradual exposure to the types of skills measured on admissions tests.
Most importantly, pay close attention to testing and application deadlines. Missing a testing window can mean losing the opportunity to apply for a particular program or school altogether.
Remember, admissions decisions should be based on your child’s overall readiness and long-term success, not simply on whether they might score a few points higher after another year. The goal is to find the educational environment where your child will be challenged, supported, and happy.
