Across the country, activists are using state learning standards, which are adopted to define what students learn, as cover for political instruction. Last week, they said so out loud.

According to Marcy Winograd, a leader of the activist group Code Pink, California history standards provide “an open door” to anti-Israel activism. She told a room full of K-12 teachers how they could promote anti-Israel politics in their classrooms and still comply with state standards. She was right.
