Gentle People, I have a large amount of data, 40,000+ rows about how students do in remedial classes including from whom they took the classes. I have pulled from it a subset of student success as relates to the separate instructors. Now I would like to extract a consolidated list of those instructors for whom the student gain on criterion based pre and post course assessments is above a specific level. I have no trouble writing if statements that will look at two types of data, the course taken and the average student increase to determine which instructors meet or surpass the criterion, but I can only do that within a list that includes all the instructors. Because there are more than an hundred such instructors, it would be easier for the dean if I could provide a short list of those that meet specific criteria. I believe that it would be an array that I should use, but I have been fooling around with this for 2 days now, and am finding myself at a series of deadends!

O knowledgeable people out there, IS this possible? If so, how on earth would I do it? Any suggestions are most welcome!
