| It certainly school's fault. Maryland has truancy laws: https://www.peoples-law.org/truancy Specifically: "Under Maryland law, a truant student is one who is “unlawfully absent” from school for more than:
8 days in any quarter,
15 days in any semester, OR
20 days in a school year." Also,
"What happens when a student is found to be truant?
The student will be referred to the county board’s system of active intervention. Note that each county must develop a system of active intervention for truant students. A school system representative will investigate the cause of the truancy. This representative may provide counseling or even notify the Department of Juvenile Services. " There is whole system designed to handle such cases and it failed miserably |
It seems very logical (however shameful) that the system would optimize for passively allowing students to age out of the system, as letting minority students fail doesn't have anywhere near as much blowback as fining or locking up disadvantaged people for truancy.
