BERKELEY -- Berkeley High School is looking for a new principal.

Pasquale Scuderi, who has led over 3,000 students at the school for four years, is staying in Berkeley but moving up to assistant superintendent.

In a note to parents on Thursday, Scuderi gave credit to himself and his team for raising the graduation rate in the last four years from 83 percent to 88 percent, dropping suspensions and growing the school's academic performance index.

Scuderi also oversaw a massive security remake at the school following a six-month period in 2011 in which seven students were caught with guns at school. It was also a time in which it was alleged that some school employees were covering up crimes on campus and when witnesses to some on-campus crimes were intimidated.

School district spokesman Mark Coplan said Superintendent Donald Evans hopes to have a replacement for Scuderi by July 1.
