Researchers and educators have begun to question whether Chapter 1 pull-out programs are the most effective method of delivering extra help to the students who need it. Pull-out programs are still the predominating type, but may be declining in popularity as in-class programs gain favor. This document summarizes a variety of program designs which are used nation-wide to provide Chapter 1 services to students. They are the following: (1) pull-out programs which provide instruction outside of the classroom and have advantages and disadvantages to student achievement and school organization; (2) add-on programs which take place beyond the regular instructional times and may cause difficulties in scheduling and transportation; (3) in-class instruction in which there is usually a Chapter 1 specialist along with the regular teacher in the students' classroom; and (4) replacement programs which provide Chapter 1 students with separate classes for all of the instruction they are to receive in a given subject and which reduce the class size for regular teachers in some areas of instruction. Research has suggested some more effective methods, but national, state, and local laws impede the success and flexibility of service delivery. A list of eight references is included. (VM)
