Parents and staff of Freedom Elementary School in Clovis who were shocked to learn that second-grade teacher Neng Yang allegedly molested one of his students in his classroom faced a sobering question: What do we tell the kids?

Parents can turn a difficult situation into a teaching moment, said Fresno clinical psychologist Thomas Granata.

"It's an opportunity for parents to talk about good touches and bad touches, if they haven't already, or to go over it again," Granata said.

Yang was arrested Friday by Clovis police on suspicion of child molestation. Monday, documents supporting federal child pornography charges revealed horrible details of repeated molestation by Yang all recorded on his cellphone camera.

Tuesday, the Fresno County District Attorney's Office filed child-molestation charges against Yang -- 45 counts from four separate occasions dating back to Dec. 8. That is nearly a month earlier than a federal investigator suggested.

Yang, 43, is scheduled to be arraigned in Superior Court this morning.

Meanwhile, Clovis Unified School District officials have been rolling out support for those most affected by the news.

District spokeswoman Kelly Avants said district officials, mindful that much if not all of the alleged abuse happened in Yang's classroom, also were reminding teachers about proper conduct.

District officials and Granata, the Fresno child psychologist, agree that parents shouldn't overreact or be overly emotional about the allegations faced by Yang.

"Children will respond the way their parents respond," Granata said.

Children may wonder whether they can still trust adults, Granata said. "We can tell them that sometimes adults do bad things, but emphasize that they are safe going to school."

Keep answers age appropriate, Granata suggested. Before answering children's questions, parents should consider "what can they understand and what's important for them to know at that age. That's different for a 5-year-old than for a 12-year-old."

After Yang's arrest Friday, district officials knew that parents and children would have many questions.

"We knew kids would have heard about it over the weekend, and we wanted to be prepared for that reality," Avants said.

On Sunday, district officials met with parents of Yang's students and teachers to prepare them for children's questions.

Teachers got a simple script to work from, and parents got a one-page list of pointers that included keeping the family routine normal, spending time with their children and answering only the questions the children ask.

When students returned to Freedom Elementary on Monday, teachers were ready to answer questions calmly and truthfully, Avants said.

"We can't act like nothing happened, but we also don't want to escalate the situation for students who may themselves not be affected by it," Avants said.

If questions persist, teachers will redirect students' attention back to their lessons, Avants said, but also will be alert to students who might need to talk to a school psychologist.

A team of about a dozen psychologists was on campus Monday. Counselors will remain at the school as long as necessary and will remain available. "There is an open invitation for parents and students to speak with them" later if needed, Avants said.

The district, Avants said, also is examining its policies for teacher-child supervision. The district will look at its practices once investigators provide more details about the case, she said.

But there are expectations in place for teachers, she said.

Clovis teachers are reminded frequently to keep classroom doors open, especially if they are working one on one with a child, Avants said.

"There is never a time that it's appropriate to be inside a classroom with a door closed, let alone door locked and lights out," she said. "You are in a position of trust, and you need to make sure your actions are of the highest standard, above reproach."

Children should be encouraged to tell their parents or a trusted adult if someone does something to them that makes them feel uncomfortable, Granata said.

"Children will always think they're in trouble," Granata said, so parents should emphasize that "the right thing to do is to tell. The girl did the right thing -- she told."

Clovis Unified trustees will hold a special closed-door board meeting today. The item for discussion is not specified but does involve an employee firing or suspension.

"We expect to have additional information after the meeting," Avants said. But she pointed to state education code that allows schools to fire an employee who faces criminal charges before their case has reached a verdict.
