MIAMI -- A grand jury has recommended the firing of more than 100 teachers, who are accused of buying college credits they did not earn.

The grand jury's recommendation follows the arrest of William McCoggle, a long-time teacher at Palmetto Senior High School. Investigators said McCoggle partnered with Eastern Oklahoma State College to provide credits for fellow teachers without class time.

Investigators said the courses that were arranged with EOSC were shams and often did not involve class time. The transcripts of the course work were so vague that teachers were able to use non-credited course work to maintain and receive certification because it appeared legitimate, according to investigators. Some teachers also used the credits for new subject area certification -- including some driver's education teachers, according to the report. Others were paid higher salaries because of bogus credits, according to investigators.

According to the grand jury report, McCoggle used a program called Move On Toward Education and Training, or MOTET, to give 189 people more than 1,600 credits between December 2002 and December 2003.

Now, Local 10 has learned that even before 2002 McCoggle used another college -- Otterbein College near Columbus, Ohio to issue credits to 629 teachers from 1999 to 2002.

Teacher Bennet Packman said that his complaints to Miami-Dade Schools Inspector General led to the investigation, eventually assisted by the FBI in Oklahoma.

"I've been notifying members of the Miami Dade school system since September 2003," Packman said.

Local 10 has learned that 15 driver's education teachers who used the illegitimate credits have been reassigned. Officials said other teachers who paid for credits issued in English and other subjects may also be reassigned.

Miami-Dade school spokesman Joe Garcia admits there were cracks in the school system's oversight.

"In cases where we actually saw recertification documentation, we need to be more careful in how we review transcripts, which is something we already took steps to take care of," Garcia said.

The ultimate approval on the phony credits came from the state Department of Education, according to investigators.

In any case, officials say procedural changes are likely.

School administrators said they are waiting to learn the names of the teachers involved. They have not yet determines if those involved will face only administrative punishment of if their actions were actually criminal.
