The Los Angeles Unified School Board announced Monday it had received and accepted the resignation of Superintendent Alberto Carvalho, effective Sunday, bringing an end to a months-long leadership crisis that began when federal agents executed search warrants at Carvalho’s home and the district’s downtown headquarters in February.

Carvalho, who led the nation’s second-largest school district serving more than 500,000 students, had been placed on paid administrative leave after FBI agents were seen removing boxes from his home in San Pedro and from LAUSD’s central office. The school board’s statement Monday said it remained “steadfast in its commitment to ensuring stability, continuity, and continued progress through strong leadership,” and affirmed that the board’s focus was “providing every student with a high-quality education, supporting our dedicated workforce, and maintaining the trust of the communities we serve.”

In his resignation letter, obtained by the Los Angeles Times, Carvalho said he was stepping down to allow the district to focus on students “without distraction.” His attorneys at the law firm Holland + Knight had previously denied any wrongdoing, stating that “no evidence has been presented by prosecutors supporting any allegation that Mr. Carvalho violated federal law.”

The FBI investigation has been tied to a review of LAUSD contracts and a failed artificial intelligence project. In 2024, Carvalho had promoted a deal with the education technology company AllHere to create an AI chatbot named “Ed” designed to assist students. The district paid AllHere $3 million but dropped the project roughly three months after its unveiling. AllHere subsequently collapsed into bankruptcy, and its founder, Joanna Smith-Griffin, was later charged with securities and wire fraud, along with identity theft. Carvalho, through his attorneys, denied personal involvement in the selection of AllHere, the Los Angeles Times reported.

At the time of the February searches, the FBI also searched a property near Miami that the Miami Herald reported belonged to Debra Kerr, a former AllHere employee who had previously worked with the company on its contract with LAUSD.

Authorities have not publicly disclosed the specific nature of the investigation, nor have they accused Carvalho of any crimes. An email to Carvalho’s law firm seeking comment Monday was not immediately returned.

The school board announced that Andrés Chait, a former teacher and principal who has been serving as acting superintendent since Carvalho was placed on leave, will remain in that position until the board makes a permanent appointment.

Carvalho became LAUSD superintendent in 2022 after leading Miami-Dade County Public Schools for nearly 14 years. His tenure in Los Angeles was marked by efforts to address chronic absenteeism, improve graduation rates, and manage the aftermath of the pandemic-era learning disruption.

The board gave no timeline for selecting a permanent replacement.
