I applied for a class and my application has been sitting. The class number is 5xx. When will my request be approved?

In most cases, classes that are 5xx are referred to as “onsites.” Onsites are classes set aside for a specific group of students. Once the Army Acquisition Training Office (ATO) has taken care of all of the students on the onsite by-name list, the ATO will fill any remaining open seats with other students that applied to the class; these vacancies will be filled by student priority level and date applied.
