Technical Note:
Because of the lack of recent data concerning how many children died, passed the GED or the CHSPE, or moved
directly to junior college rather than graduating high school, we lowered every county's dropouts by the 1998 statewide
factor of 4.9% when calculating the CPEC Adjusted Dropout Rate.
