The Board of Education is expected to vote next Tuesday on the recommendations for Magnolia Science Academy 1 in Reseda, Magnolia Science Academy 2 in Van Nuys and Magnolia Science Academy 3 in Carson.

Magnolia’s schools have attracted increased attention in the wake of a failed coup in Turkey in July. The government of Turkish President Recep Tayyip Erdogan has accused Turkish cleric Muhammed Fethullah Gulen of masterminding the revolt. Erdogan claims American charter schools with Turkish ties supported — and even helped fund — Gulen’s alleged activities.

L.A. Unified has not yet released its rationale for recommending that the schools’ renewal requests be denied. But sources inside and outside the district make it clear that one major issue is Magnolia’s foreign workers, most of whom came in to teach.

The school group applied to bring in 138 teachers from abroad, almost all from Turkey, and 97 eventually worked for Magnolia. Thirty-seven still do. As required by law, Magnolia covered the visa-related costs, which it estimated at about $3,000 per employee, and chose to pay for the visas of spouses and children.

L.A. Unified estimated the total cost of that effort at about $929,000, according to Magnolia Chief Executive Caprice Young, the former L.A. school board president who took over Magnolia in 2015.

Young said she ended the practice, though she has brought in a Chinese citizen to teach Chinese.

L.A. school board president Steve Zimmer, however, says Magnolia’s past actions remain a problem. Magnolia never indicated it intended to import teachers en masse, Zimmer said, when before the Board of Education for approval.

“The role of an authorizer includes making sure that a charter follows the instructional and business practices outlined in its petition,” said Zimmer, who declined to discuss the district’s internal report.

The significance of any alleged ties to Gulen is a matter of intense debate. The cleric, who lives in self-imposed exile in Pennsylvania, has denied involvement in the coup. And Turkish-associated charter groups, including Magnolia, have denied financial or management ties with each other or with him.

Magnolia’s Turkish employees agreed to be interviewed only on condition of anonymity, out of fear that family members back home could be targeted in a wide-ranging crackdown on dissidents and suspected Gulen followers. Magnolia governing board member Umit Yapanel recently stepped forward as an admirer of Gulen, he said, to emphasize the peaceful intentions of like-minded people.

“In discussing whether the schools should be renewed, L.A. Unified officials will bring up the spending of public education funds on the visas, the employment of foreign nationals over American workers and the failure to disclose the hiring strategy, said district sources who were not authorized to speak on the record. The work visas, known by the designation H-1B, are supposed to be used only when no qualified American job seekers can be found.”
