influence they had on each activity on a scale of 1 to 6, where 1 represented none and 6 represented a great  deal.  The 1993-94 questionnaires used a 0 to 5 scale, and 1993-94 scores in this table have been adjusted to the 1 to 6 scale.SOURCE:  U.S. Department of Education, National Center for Education Statistics, Schools and Staffing Survey: 1987-88 (School Administrator, Public and Private School, and Teacher Demand and Shortage Questionnaires), 1990-91 (Public and Private School Administrator, Public and Private School, and Teacher Demand and ShortageQuestionnaires), and 1993-94 (Public and Private School Principal, Public and Private School, and Teacher Demand and Shortage Questionnaires).
