An embattled school district chose caution over spectacle. Rather than gamble on a headline-grabbing outsider, the Los Angeles Unified School District turned inward, elevating longtime insider Andres Chait to lead at one of the most turbulent moments in its recent history. The move came after the board voted unanimously to place Alberto Carvalho on paid administrative leave pending an investigation. Chait was named acting superintendent, effective immediately. At 51, Chait is not a reset button.
