acceleration is the most effective intervention for students who are ready for challenge and advanced curriculum. The flip side isn’t as shiny. Students who are not challenged become disengaged from school and their joy of learning goes away.
There are more than 20 forms of acceleration and some are extraordinarily effective, in particular grade-skipping and single-subject acceleration.
Research with tens of thousands of students documents that the vast majority of accelerated students make a good adjustment socially and emotionally, and there are no ill effects.
