Harrison selected as Manteca Adult School principal

Bradley Harrison is replacing Diane Medeiros as Manteca Adult School principal when she retires next month.

The Manteca Unified board appointed Harrison last week. Harrison has spent the last 8 years as the Weston Ranch High vice principal and has been employed by the district for 28 years.

“Principal Medeiros will be difficult shoes to fill as her dedication to students and families has spanned a career of 33 years,” noted Senior Education Director Clara Schmiedt.

 Manteca Adult School — that conducts most of its classes at the Manteca Unified district complex at Louise Avenue and Airport Way — does more than just help adults who did not  secure a high school diploma to earn their GED  equivalency.

The Manteca Unified offers adult basic education, English as a second language, citizenship preparation, high school diplomas and courses — including assessment and certificate — needed to change careers.

 And in order to be more flexible and accessible for working adults, Manteca Adult School two years ago switched from two 15-week semesters to four nine-week sessions.

Manteca Unified has been making the career training portion of the adult school more robust in recent years to reflect the changing job market. 

Harrison said he is “excited, humbled, and challenged by the opportunity to ensure adult education is accessible to everyone in the school district community” and looks forward to helping adult students thrive by having access to ongoing education.

Weston Ranch High Principal Troy Fast had high praise for Harrison.

“Making an impact through rigorous curriculum design, school wide leadership, implementing a freshmen transition program, and direct math intervention programs, Mr. Harrison is an instrumental leader of the Weston Ranch team and will certainly be missed,” Fast said.
