A pilot project was conducted to implement the Oregon A.I.M. (Assessment, Instruction, Mastery), a tutor program accountability system developed in Oregon, in 15 volunteer-based programs in Pennsylvania and to make recommendations on the usefulness of this system as a means of collecting and aggregating data on student progress for these and similar programs. During the project, 100 tutors and program staff from 15 programs attended training workshops on the use of the A.I.M. system. Over the program year, 131 tutors and program staff used the assessment with 169 students. Tutors liked the A.I.M. because they were able to see concrete evidence that their students were learning. Students were pleased because they were tested on an ongoing basis and in situations in which they were comfortable. Program staff noted that the materials gave them an additional means of reporting success that was directly related to many of the real-life goals of the students. The project concluded that the competency lists of the A.I.M. can be a way to bring uniformity and validity in measurement to individualized goal-oriented literacy programs. The process was enthusiastically received by the literacy programs involved. A training process was developed and will be used in continuing the program for an additional year. (Survey results, A.I.M. checklists, and examples of evidence of mastery are included in the report.) (KC)
