Other schools report improved attendance and increased parent involvement. Looping also gives a lot of bang for the buck. Because it focuses on individual classrooms instead of the entire school, it is relatively low-risk. It is also relatively inexpensive to implement, except for teacher workshops in new content areas and team-building to ease the transition.

People are most comfortable doing what they grew up with.
All you're selling is a strong bonded relationship over two years. Parents fear getting stuck with a weak teacher two years in a row, while teachers worry about a second year with a difficult child or miserable parent. But poor teachers, looping advocates point out, rarely volunteer for the job because it means learning two curriculums. In some states, there could also be contractual issues, such as whether the job must be posted or if looping will affect seniority. Like any educational practice, there is no one way to implement looping.
