In addition to collecting data in new exit categories, the method of analyzing these data has also changed. Rather than calculating percentages based on the number of total exiters with disabilities as in the past, percentages are now calculated based on total child count for students ages 14 and older. This revision was made primarily to make OSEP dropout rates comparable with rates used by other Federal agencies. Readers must keep in mind that not all students ages 14-21 will exit special education each year, and, as a consequence, percentages of exiting students will not sum to 100 percent.6 The new rates, as shown in figure 1.1, indicate the annual rate at which students with disabilities 14 and older continue to be enrolled in and exit special education through the various bases.
Among the 1.6 percent of students who graduated with a certificate of completion or modified diploma, students with mental retardation (3.8 percent of all students with mental retardation ages 14-21) and deaf-blindness (4.6 percent) were most likely to graduate in this manner. Graduation with a certificate of completion or modified diploma was also common for students beyond the typical age for secondary school students; during the year, almost one-fourth of all students ages 21 and older received a certificate or modified diploma.
During the past 5 years, the percentage of all students with disabilities ages 14 and older graduating with a diploma or certificate has remained fairly constant, although the percentage decreased slightly in 1993-94, as shown in figure 1.2. The decline in the percentage of students graduating in 1993-94 reflects a smaller proportion of students receiving certificates of completion and modified diplomas. Some of this decline may be accounted for by policy changes in the States. For example, Texas no longer offers students with disabilities a modified diploma.
Because this was the first year data were required on students returning to general education, the percentage reported as returning is expected to increase over the next few years as States continue to modify their data collection systems. There were a small number of States and Outlying Areas that did not report any students returning to regular education, presumably because their State and local data systems were not prepared to process these data. Because percentages are based on the national child count for students 14 and older, nonreporting tends to lower national estimates slightly.
In a recent Michigan study, the authors analyzed data on the number and characteristics of students ages 6-26 who had returned to general education through declassification, and the results of a one-year followup of declassified students. Figure 1.3 shows the number of students declassified in Michigan by age and disability.

The largest numbers of students who were declassified were in the upper elementary age ranges, although declassification continued through early adulthood. The students declassified at younger ages were more likely to have speech or language impairments. Students declassified in secondary school were more likely to have learning disabilities or serious emotional disturbance (Carlson & Parshall,1995).
Michigan teachers and school counselors reported generally positive academic, social, and behavioral adjustments for declassified students who returned to general education programs. However, teachers and counselors of 11 percent of declassified students indicated that, in their opinion, the students continued to require special education services. Students with serious emotional disturbance were most likely to be perceived as in need of additional special education support (Carlson & Parshall, in press).

In the course of the year, 8.3 percent of all students with disabilities ages 14-21 moved to another district or State (see table 1.6). Of that 8.3 percent, 5.5 percent were known to be continuing their education in another district or State. There was insufficient information to determine whether the other 2.8 percent were enrolled in another district or State.
By far, students with serious emotional disturbances moved most often. Annually, 16.4 percent of all students ages 14-21 with serious emotional disturbance move, almost twice the rate of any other disability group. It is not clear if this rate occurs because students with serious emotional disturbance move in search of special education services, or for some other reason.
The annual dropout rate for students with disabilities at each individual age can be combined to estimate a cohort dropout rate. The cohort dropout rate estimates the percentage of students who will drop out over the course of their entire high school careers. Given current trends, approximately 26 percent of students with disabilities will drop out of school. 7
The U.S. Bureau of the Census (1995) collects data on annual and cohort dropout rates for students nationwide. The Census Bureau reports an annual dropout rate of 5 percent for students in grades 10-12, the same as the rate for students with disabilities ages 14-21, and a cohort rate of 13.3 percent for persons ages 14-24. The discrepancy in cohort rates may be a result of differences in dropout recovery rates among students with (26 percent) and without (13.3 percent) disabilities, which directly influence the cohort dropout rate, but not the annual rate. Data suggest that dropouts with disabilities are far less likely than dropouts without disabilities to eventually earn their high school diploma.
7 Based on 1993-94 data presented above, annual event dropout rates for ages 14-17 and 18-21 are 0.9 percent, 1.8 percent, 5.2 percent, 7.8 percent, and 13.2 percent, respectively. If one begins with a group of 1,000 14-year-olds, 0.9 percent (9) drop out at age 14 and 991 remain. Of those remaining, 1.8 percent (18) drop out at age 15; 973 remain. At age 16, 5.2 percent (51) drop out, leaving 922. At age 17, 7.8 percent (72) drop out and 850 remain. From ages 18-21, 13.2 percent (112) drop out, leaving 738. The cumulative dropout rate is (9+18+51+72+112)/1,000=26.2 percent.
