In the last boundary change which took place in 2014, Crestwood and 16th Street Heights were assigned to MacFarland and Roosevelt. However, MacFarland was closed at the time and was going to open as a bilingual school. Therefore, the two neighborhoods were grandfathered to Deal (but not to Wilson/JR) until 2022. Last school year, residents of the neighborhood should not have been allowed to enroll in Deal. However, DCPS apparently continued the grandfathering. The most recent boundary change which will be in effect for the 24-25 school year does not have the grandfathering. Therefore, the official middle school for Crestwood and 16th Street Heights is MacFarland and the high school is Roosevelt.
Any student who goes to Deal is allowed to go to JR due to the feeder pattern. Therefore, students who attended Deal during the grandfathering were able to go to JR even though that was not their assigned high school.
After saying all of this, who knows what Deal's registrar will do. It is probably equal money that students from Crestwood and 16th Street Heights will still be able to enroll.
