Portland Public Schools officials have asked parents to take down a protest video filmed on school property. The YouTube video shows students holding signs, as they’re gathered near the Sabin School playground.  

A producer of the video told the Portland Tribune that the request from the district feels like an attempt at silencing dissent.

A district spokesperson says its priority is protecting student privacy. The district says it supports parents expressing their opinions, but it requires they get advance permission to record at a school.  

The video is aimed at pressuring the district to reduce class size. The Sabin principal has said he’s hiring another teacher to reduce class size in first grade. Parents are still concerned about other grade levels.
