Greenwich school officials say Central Middle School students will be relocated to other buildings when classes resume on Monday.

An engineering report in January found that the school building had “significant structural concerns.” District officials say crews are working to make the building safe so it can reopen as soon as possible.

All grades will have a two-hour delayed opening on Monday.

Starting this week, sixth graders will be moved to Cos Cob School, seventh grade to Eastern Middle School and eighth graders to Greenwich High School.
