P.L.A.N. (Planning and Learning with Accordance to Need) was a 1970's era school curriculum which was designed to allow students to learn at their own pace without the need of traditional classroom instruction (i.e. a teacher lecturing in front of a blackboard). A worksheet called a TLU (Teacher Learning Unit) was used for instruction along with various other workbooks. TLU's came in different grade levels for each subject. There were no standard tests or exams. Instead, students went through as many TLU's as they wished (a TLU was completed by taking a multiple choice test on IBM style computer cards). Pupils, however, were expected to complete at least one TLU per week. Curriculum
