Older kids generally succeed better in sports, but holding kids back in school seems to have the opposite effect when it comes to academic achievement.
The researchers discovered that relatively more mature students didn’t have an academic edge; instead, when they looked at their progress at the end of kindergarten, and, later, when they reached middle school, they were worse off in multiple respects. Not only did they score significantly lower on achievement tests — both in kindergarten and middle school — they were also more likely to have been kept back a year by the time they reached middle school, and were less likely to take college-entrance exams. The less mature students, on the other hand, experienced positive effects from being in a relatively more mature environment: in striving to catch up with their peers, they ended up surpassing them.
I was the second youngest kid in my class growing up; only our valedictorian was younger. Meg was young too. And both our kids are among the youngest in the class…we didn’t redshirt them because they seemed ready for the grades they’re in. As the article states, the differences are starker now than they were…some kids in their groups are more than a year older than they are and most are several months older. NYC preschools have trouble finding a wide range of ages for each class because so many people are holding their kids back to gain a supposed competitive edge against their peers…fall kindergarten classes are full of 6-year-olds but few just-turned-fives. It’s crazy…but so much of New York is competitive like this, why wouldn’t kids’ preschool education be the same?
