Eighth- and 9th-graders who applied to high school last fall but were not matched to any school, or who wanted to apply to a different school in a second round of applications, learned the results of their new application this week, the Department of Education said.

In the first round of admissions, about 8 percent of 8th-graders applying for 9th grade got no match, forcing them into a second round. Other students chose to re-apply to different schools that still had open seats in March.

Students who are unhappy with their high school assignment, or whose circumstances have changed since they applied, now have the option to appeal and try for a different school. Appeal forms are available from school guidance counselors now and are due back on Wednesday, May 20.

Will an appeal be successful? It depends on the reason. See our advice on how to appeal. And, for a look at the number of appeals granted in recent years, and which type of appeals were most commonly approved between 2011–2013, read "Kids win one-quarter of high school appeals."
