List the Special Ed students who have dropped out. Use this search and change the entrydate to the first day of school for the previous year. /S_VA_STU_X.Primary_Disability_Code#;exitCode contains W8;entrydate>=8/10/15
The Fall Dropout Report is actually for the previous year so you'll need to use the first day of the previous school year. In this case it would be 8/10/2015. They wait until after the Fall SRC report is complete just to make sure the students don't show up in the fall after dropping out in the previous school year.
