Fired Poway Unified School District superintendent John Collins can no longer teach or manage public schools in California.

The California Commission on Teacher Credentialing revoked Collins’ teaching and administrator credentials effective July 23 due to “misconduct,” according to the commission’s website. No other details about the action were immediately available.

The Poway school board fired Collins in July 2016 after forensic auditors found vacation cash-outs and compounded longevity pay boosted his compensation above the amount afforded in his contract.

Poway Unified sued Collins that same month in civil court alleging fraud, and is seeking to recover more than $300,000. The lawsuit also accused Collins of using district money to seek restraining orders without board approval, among other issues.

Collins’ conduct as superintendent is also under review by the San Diego County District Attorney’s Office, though no charges have been filed.

Collins, who has previously denied any wrongdoing, did not respond to an emailed request for comment Wednesday. A request sent to Collins’ attorney Paul Pfingst was not answered.

A case management conference in the civil case is scheduled for Sept. 22, according to court records.

Once a credential is revoked, educators may apply for reinstatement after one year.
