The latest letter from Diaz could put an end to a saga prompted by Florida education officials pressing the College Board in May about whether the nonprofit’s courses fell in line with state rules prohibiting most lessons on sexual orientation and gender identity in public schools. The nonprofit at the time pushed back on Florida’s attempt to influence lessons under the guise of parental rights law, referred to as “Don’t Say Gay” by critics.

The College Board’s claims that the course was banned sent some schools scrambling to find replacements last week while others were left weighing their options with mere days before classes start.

To illustrate how quickly things changed in Florida, officials schools with Palm Beach County School District announced Wednesday that local campuses will offer AP psychology just one day after apologizing for axing the course.

“If there was a way we could teach this course and not have our teachers get arrested, we would do it in a second,” Mike Burke, Palm Beach’s school chief, said Tuesday morning at a back-to-school breakfast, as reported by the Palm Beach Post, before the district reversed course.

Some school districts quickly dropped AP psychology and instead are offering Cambridge Advanced International Certificate of Education, or AICE, and International Baccalaureate programs. One district — Pinellas — ordered new AICE textbooks the same day it was announced the AP course could be disallowed.

But other districts trudged forward with the AP course, even before Diaz clarified the state’s stance on Wednesday. Broward County, as one example, is asking parents to “opt in” for students to take the course. Schools in Leon County, meanwhile, are moving ahead without such a designation.

“I have communicated to our staff to respect the law and follow the law, but not to fear the law and do more than it requires,” Leon County Schools Superintendent Rocky Hanna said in a statement Tuesday.
