The entire Chicago Board of Education is expected to resign later this month, amid a dispute with Mayor Brandon Johnson over the fate of Chicago Public Schools CEO Pedro Martinez, Johnson's office and the board confirmed Friday afternoon. In a joint statement, the mayor's office and the school board cited the upcoming shift from a board appointed entirely by the mayor to a partially elected board. Voters in November will choose 10 board members, while Johnson will appoint 10 others, as well as the board's president. None of the current board members planned to continue serving on the hybrid board when it is seated in January.
