An LAUSD spokesperson confirmed to Eyewitness News that the district received a letter of resignation from Alberto Carvalho.
"It has been a great honor to serve you," Carvalho wrote in a letter addressed to "the students, families, teachers, staff, and community of LAUSD," the Los Angeles Times reported. "Over the past four years, together, we have made historic progress - gains that belong to our students, our educators, staff and our communities."
In the letter, Carvalho pointed to accomplishments under his tenure, including record-high graduation rates and a reduction in chronic absenteeism.
"Placing students first has always guided my work. Because I believe our schools must remain focused on students and learning without distraction, I am resigning as superintendent of LAUSD," the statement continued.
According to the Times report, Carvalho didn't directly address why he was stepping down from his position.
The district's Board of Education released the following statement after Carvalho's resignation was announced:
"The Board remains steadfast in its commitment to ensuring stability, continuity, and continued progress through strong leadership. Our focus remains unchanged: providing every student with a high-quality education, supporting our dedicated workforce, and maintaining the trust of the communities we serve."
Acting Superintendent Andrés Chait will remain in the position until it can be permanently filled, officials said.
On Feb. 27, two days after the FBI conducted searches at Carvalho's home and LAUSD offices, the district's Board of Education voted unanimously to place him on leave pending the outcome of the probe. He has been on leave since then.
"Mr. Carvalho remains confident that the evidence will ultimately demonstrate that he acted appropriately and in the best interests of students," said a statement released in March, attributed to a spokesperson for Carvalho. "We hope the school board reinstates him promptly to his position as superintendent."
Authorities have not charged Carvalho with any crimes. The investigation is possibly tied to district contracts, though federal authorities have not provided details on the nature of the investigation.
"I got surprised. I didn't really thought that he was going to resign because he was under investigation. Nothing has come out yet. If it's true what he did or not, they never said anything, so it's still under investigation," said Ana Ramirez, a parent of LAUSD students. "I hope whoever comes brings something good for them, for the kids, because there's a lot of things that are not OK. Every school is different, but yet, it feels like parents don't get heard in schools."
For its part, United Teachers Los Angeles released a statement saying, in part, "The next superintendent must ensure that district resources are invested where they matter most: in our schools and classrooms, not in billions of dollars' worth of outside contracts."
The FBI also searched a third location near Miami. The Miami Herald reported the Florida property belonged to Debra Kerr, who previously worked with AllHere, an education technology company that had a contract with Los Angeles schools before it collapsed, and its leader was indicted for fraud.

In 2024, Carvalho heavily touted a deal with AllHere for an AI chatbot named "Ed" designed to help students. But about three months after unveiling the technology and paying the company $3 million, the district dropped its dealings with AllHere, which collapsed into bankruptcy. Months later, founder Joanna Smith-Griffin was charged with securities and wire fraud, along with identity theft.
At the time, Carvalho denied personal involvement in the selection of AllHere, according to the Los Angeles Times.
"Mr. Carvalho respects the rule of law and the investigative process and has always acted in the best interests of students and within the bounds of the law," the statement said. "While the government's investigation remains ongoing, no evidence has been presented by prosecutors supporting any allegation that Mr. Carvalho violated federal law."
Following the search of the school headquarters, LAUSD said it was cooperating with investigators.
Carvalho became superintendent for L.A. in 2022. He previously led the public schools in Miami.
