Francis Foster argues that modern teachers are forced to teach political ideology.

The finding

What the evidence shows

There are real, documented controversies over political bias in UK classrooms, including accusations that some schools have pushed one sided material on students. But 'forced' overstates it: official UK government guidance requires teachers to stay impartial and present balanced views on contested political issues, and explicitly tells them to avoid promoting their own opinions, so there's no national policy mandating ideological teaching. The complaints are about individual schools or teachers allegedly not following that guidance, not a system wide mandate.
