This first section of this report profiles the first five Alternative Routes to Certification (ARTC) cohorts (1997-98 through 2001-02), including patterns of district and school participation and characteristics of all 164 candidates enrolled by district during the first 5 years. It addresses the question of who participates in ARTC. The second section considers patterns of attrition among candidates in the first four cohorts, examining whether those who complete their ARTC courses differ from all candidates enrolled or from those who do not complete their courses. The third section summarizes key findings from a follow-up survey of supervisors of the first four cohorts, discussing whether those who complete their ARTC courses stay and succeed in Delaware schools and focusing on retention, certification status, tenure status, and overall performance. The fourth section presents current completion and enrollment projections for the 2001-02 and 2002-03 cohorts. The fifth section summarizes the report's major findings regarding patterns and prospects (meeting goals, patterns of growth, changing enrollment patterns, who succeeds and who does not, and future directions). An appendix presents the survey of supervisors of ARTC graduates, February 2001. (Contains 16 tables and 6 figures.) (SM)
