The special education teacher at New Brunswick High School missed 33 days, including 23 unpaid days, during the 2006-2007 school year. School officials asked for medical documentation to explain the missed time.
Authorities say Williams tried to justify the absences after he obtained a forged prescription blank with the name of a Newark pediatrician.
Under a plea agreement, Williams pleaded guilty to a count of uttering a forged instrument.
