Don't miss this on hold harmless!

 I have been saying that this is the story of FY22 for Massachusetts schools: 

Implementation of the Student Opportunity Act is having to push against the statewide drop in student enrollment in order to make any headway in the decades' old underfunding of education in Massachusetts.

What would help? Hold harmless enrollment. 
This EdTrust piece talks through (from a national perspective) how that would work, with key emphasis on hold harmless for enrollment categories, too.
