A student is considered a dropout if he or she was enrolled at any time during the previous school year, is not enrolled at the beginning of the current school year, and does not meet certain exclusionary conditions (NMPED 2008-2009 New Mexico Student Dropout Report,
The time frames represent school years (SY).

The SY 2014-2015 data are the most recent available; retrieved May 2017.
According to the most recent publication from the The NM Public Education Department (NMPED), dropout rates are not related to cohort on-time graduation. The term "dropout" relates to something different from a "non-graduate," so the rates are not complementary--that is, subtracting the rate of non-graduates from the rate of on-time graduates does not yield the dropout rate. In addition, dropout rates are calculated each year, unlike on-time graduation rates.
It is important to note that the reported dropout rates reflect an "overall rate", namely for grades 7-12, which include but do not exclusively reflect high school dropout rates. High school dropout rates are significantly higher than for middle school. The NMPED historically has reported overall rates.
The reported data are for public and charter schools statewide.
