I am currently reading Forbidden Language, by Patricia Gandara and Megan Hopkins, and I am astonished by the statistics quoted related to the high drop out rates for EL students.

Does anyone know where I can get more information on this subject?

Here is one summary : In particular, dropout rates are significantly higher for Blacks, Hispanics, and Native Americans than for Anglos and Asian students.
