This report contains information on the participation of nonpublic school students in Chapter 1 programs. Regulations for Chapter 1 services require that all students have equitable access to them. In some school districts the nonpublic school population is not served because officials or parents of these schools do not want to participate. Since 1984-85, the number of districts providing Chapter 1 services to nonpublic school students has remained fairly constant, but the number of nonpublic school students participating in these services has decreased from 180,700 to 130,600. A Supreme Court decision in 1985 made many districts alter the location of Chapter 1 services, so that from 1984-85 to 1986-87, the proportion of districts that provided Chapter 1 instruction to nonpublic school students inside the students' own nonpublic school decreased from 76 percent to 10 percent. Some of these students now receive Chapter 1 instruction in mobile vans or at another site because Chapter 1 teachers and aides can no longer give services inside schools affiliated with religious organizations. Another method of providing services is through technical means such as computer-based instruction. Twelve tables present the statistical data for Chapter 1 services. (VM)
