PLEASANTON (KPIX 5) — Less than a month after a teacher at a Pleasanton preschool was accused of tying up a toddler, the school faces new scrutiny after a student was allegedly pinched by another teacher.

The latest incident happened on the grounds of the Centerpointe Christian Preschool sometime in the month of February, according to a complaint investigation report filed by the California Department of Social Services.

“A child was pinched on his side and had his arm squeezed by a staff member,” the report said.

This new investigation involves a different staff member and is a completely separate from an incident that was reported last month. Former teacher Angela Calcagno was accused of tying up a 2-year old with tape after the child refused to take a nap.

According to an email released Wednesday by the preschool, the pinching incident actually happened first, on an uncertain date in February, but it was not reported until after the taping incident came to light.

The report said a parent told the pastor, and that the pastor correctly and immediately passed the information on to the state.

“We have a strong commitment to take all reports regarding our program seriously, investigate them, and communicate the outcomes in a timely manner,” said the statement to parents. “The person involved was a substitute teacher.”

That substitute teacher no longer works at the school, according to the email. Church officials said they have recently put staff members through an extensive training process to identify what they call “personal rights violations” of students. They stress that both of the incidents happened before the training.

Because it was the repeat violation within one year, the state has leveled a civil penalty against the school of $150.
