For years, Manteca Unified residents who took classes in the Manteca Adult School for their General Equivalency Education, or GED certificate, and to learn English as a Second Language did not have to pay a fee. That has changed in the 2012-13 school year that just started. Students who enrolled in those classes had to pay a “modest registration fee” this time - $30 each for GED and $25 for ESL classes plus $30 for the workbook.
