The number of public high school graduates, which had been decreasing for the past 10 years, is projected to increase through 1988-89. After 1988-89, the number of public high school graduates is projected to begin decreasing once again--at least until the early 1990s. The data used in these forecasts were obtained from the Common Core of Data (CCD) survey conducted by the Center for Education Statistics. No comparable source of this type of data exists for private schools. (MLF)
