evidence: But as schools increasingly become a battleground in American politics and Gov. Ron DeSantis eyes a potential presidential bid, an emboldened Republican supermajority in the Legislature is renewing efforts to make changes to the state’s K-12 education system and the local authorities that oversee it. [...] The Florida Education Association, the largest union in the state, said the bill was about "revenge," as teachers unions played a key role in supporting DeSantis’ Democratic gubernatorial opponent, Charlie Crist, and his running mate, Karla Hernández-Mats, who is the head of United Teachers of Dade. Easing up on certifications: DeSantis has signed into law a measure that will make it easier for teachers to get certifications by creating additional methods to demonstrate the expertise required to be certified. For example, the requirement of mastery of general knowledge will be waived for an individual who has been provided three years of support and instruction and who has been rated effective or highly effective for each of the previous three years.
