The Process Analysis of Non-Grading (PANG) project was initiated from experiences in a small school pilot study of a nongraded school system in Sweden. This small school suggested a nongraded upper comprehensive school (pupil age 14-16 years). Since 1972 the PANG project has successfully worked out a nongraded system at the secondary level in four one-class schools and one two-class school. In the comparison schools, chosen from districts of the same economic, social, and employment structure, the classes mostly contain pupils who live at a boarding-house in the central village during the week. During the 1975-76 school session, the total situation and development of the pupils in the nongraded school system and in the graded system in a school far away from home will be analyzed. This analysis will encompass two main areas: (1) the instructional situation--factors concerned with the educational process in the nongraded system and its effect on pupil attitudes and knowledge compared to a traditionally graded system; and (2) the social situation--factors which consider how the pupils' situation at home, among friends and within the community changes when changed from one teaching system to another, from one living place to another, and when transportation circumstances change. This report describes how this analysis will be conducted. (NQ)
