Enrollment Data taken from http://www.tea.state.tx.us/adhocrpt/Standard_Reports.html
Eighth Grade Class of 2005 at Quintanilla, the first to write letters for Archive, were never able to see the Archive as it was installed after they left for high school.
8th Grade Class of 2006 at Quintanilla were the first class to write letters for Archive and have their photos taken in front of the Archive with their Language Arts Class.
8th Grade Class of 2007 were the first class at Quintanilla to both have their photos taken holding their letters and then to each place their letter into the Archive themselves.

Conclusions from above enrollment patterns:
1) Initially in 2005-2006 9th grade enrollment went up at both high high schools possibly showing that more Quintanilla students went on to high school.
2) For the next two years at each school 9th grade enrollment went down, hopefully indicating that fewer students were failing 9th grade each year at each school.
3) Additional indications that fewer were failing 9th grade each year is found in the fact that 10th grade enrollment went up every year at each school.
4) The 9th to 10th grade dropout rate constantly went down during these three years at both schools. By the third year it had gone down 5 percentage points at Pinkston, from 38.9% to 33.9% and 8 points at Sunset, from 33.0% to 25.2%.





A study selecting out for Quintanilla students at these two schools would verify the amount Quintanilla students, and possibly the Archive Project, contributed to these enrollment changes over the past 4 years.
