The appropriateness, or otherwise, of grade acceleration really depends on the individual child. My daughters were both early entrants and thrived, mainly because, as their school principals in both primary & secondary schools commented, no one would ever have guessed that they were younger than their classmates as they were globally advanced, so much so that when they competed at sports in their correct age group, their eligibility would often be questioned by other parents.
My son’s development was initially more asynchronous and it was absolutely the right call to keep him with age peers and advocate for radical subject acceleration.
