SAN FRANCISCO (KRON) --The San Francisco Unified School District reported in September that 350 teachers were found to not have proper credentials and over 200 special education teachers and aides were not hired because the district did not issue funding for these roles. More than 300 teachers lacking credentials, says SFUSD The Board of Supervisors are now holding an emergency hearing on Tuesday to discuss these ongoing issues. "One-hundred fifty of them are called paraeducators. Those are the ones that come in and give support to the special education students," said San Francisco’s District 11 Supervisor Ahsha Safaí. "Then there's an additional layer of instructional teachers, special education teachers, that have not been hired; it's like another hundred. There was a request initially for $60 million in additional [funding]. They realized that it only needed to be $30 million but then that still got delayed by months which then delays hiring and then delays instruction and support for special education students and that's wrong." Supervisor Safaí is leading the hearing set for Tuesday. The number one question on many people's mind is, how did this happen? "I met with the superintendent this morning, asked him the same question," Safaí told KRON4 News. "He needs to hold himself accountable, and I think he will, and we're going to get into that, 'how did we get here?' I'm not really interested in finger pointing. But we're interested in making sure that this doesn't happen again...I told the superintendent to come ready to answer that question and don't give an evasive answer. You're just going to make people angry. People want to know." The district is federally mandated to offer these services and the exact number of students impacted remains unclear. KRON4 News contacted SFUSD about this, but they did not provide any new information. By not providing these contractual services, the district could face legal challenges or lawsuits. "For every hour that is not afforded to a child who is in an individual education plan, the Unified School District is in breach of their contract and they are required to actually compensate those families for the instructional hours lost," said Safaí. KRON4 News reached out to the United Educators of San Francisco, the teachers' union and Mayor London Breed's office, but we have not heard back as of this report.
