Graduates from the entire cohort of 9th grade students at the time the class graduates.
TEA began rolling introduction to the NCES dropout definition with the class of 2006. Because the methodology is new, comparisons to rates for Class of 2005 or earlier are invalid. Furthermore, dropout rates for the classes of 2006, 2007, 2008, and 2009 cannot be compared to each other because the new definition is being implemented on a rolling basis. In other words, the 2006 longitudinal dropout uses the old state definition for the freshman through junior years and the new definition for their senior year. For the class of 2007, TEA calculates the first two years and the NCES definition for the last two years, etc. See table 2, on p.6 of TEA's 2006-07 dropout report at: http://www.tea.state.tx.us/research/abs2.htm#Dropout.
The number and percent of births to women who received no prenatal care, or care after the first trimester.
In 2005 Texas introduced a new birth certificate, changing the categorization of the inadequate prenatal care data. Now, inadequate prenatal care is defined as receiving no prenatal care or only receiving prenatal care after the first trimester. Data from 2005 or later cannot be compared to earlier prenatal care data.
