The Applied Research Center has a report by Mattie Weiss called "Youth Rising". This is not solely a report on undocumented youth, but they are included, and in the context of multiracial coalitions, as it seems from the explanation online.

Supposedly, you should be able to download the PDF for free (and it's 128 pages, so they are being awesome generous). I had some problems and called them- they are working on it, and it will hopefully be up in a day or two (i am writing this on 8/27/07).

I have also found a master's thesis from San Jose State University:
Challenging educational barriers: Undocumented immigrant student advocates
by Villegas, Francisco J., M.A., San Jose State University, 2006, 99 pages; AAT 1438598
Abstract (Summary)
Undocumented Latina/o students who make it to the university contend with stressors related to race/ethnicity, undocumented status, gender, and socioeconomic status. The purpose of this study is to examine the experiences of Latina/o undocumented students in higher education. This study examines the barriers undocumented students experience in their pursuit of higher education. A secondary endeavor is determining whether the degrees they achieve will be useful. The study relies upon qualitative data, specifically field observations and seven semi-structured interviews conducted during the 2005-2006 academic year in a Bay Area university. Preliminary findings indicate that students are resilient in their academic endeavors, rely upon several sources of support including peer, familial, and institutional opportunities, and they advocate on behalf of other students. The analysis indicates that there is a need for further advocacy and research to address this vital population of students central to U.S. society and the nation's economic future.
