Wilburn implemented the Teacher Advancement Program (TAP) from 2008-09 through 2014-15. TIF [Teacher Incentive Fund] funding supported the performance pay component since 2010-11. All TAP principles were implemented. However, challenges occurred related to staff turnover, scheduling, and the extra work involved. Many teachers did not find the TAP model very helpful. The TAP rubric and model lessons (with coaching) were considered the most positive aspects. Relative to the comparison schools, the pattern of K-2 literacy results was mixed for 2013-14 and somewhat stronger in 2014-15. Wilburn also showed similar patterns for the percentage of students scoring proficient on the EOG from 2007-08 (before TAP) to 2011-12 and 2012- 13 to 2014-15 (with the revised EOG). Wilburn's growth results on EVAAS were at or above state expectations each year except for grade 4 in both subjects in 2015. Results were similar to comparison schools (with somewhat stronger results in 5th grade math). Overall, Wilburn achievement results have not been consistently stronger with TAP compared to similar schools without TAP. The cost/benefit of the model was not clearly favorable.
