A Texas high school postponed its graduation so 28 of its 33 seniors — or nearly 85% — can meet eligibility requirements to graduate.

The seniors of Marlin High School were scheduled to get their diplomas on Thursday but, according to Texas station KWTX, students will now graduate at some point in June, once summer school has ended.

Incompletion or failure of required courses, as well as absences, are reportedly to blame for the majority of students’ ineligibility.

Some parents at a Wednesday night meeting blamed educators and administrators for student shortcomings. Administrators pushed back, claiming pupils in bad standing were made aware of their situations and will be better served by earning a diploma than being handed one that’s “not worth the paper that it’s printed on.”

Victoria Banda said she was surprised by a phone call informing her that her son would not be graduating due to a history test he hadn’t completed.

“We have family traveling in from Mexico,” Banda complained. “And if anyone knows, it’s not cheap.”

Marlin, Texas is roughly 30 miles south of Waco, near the center of the state. It’s home to nearly 5,500 residents.

Alondra Alvarado, who was one of the few who did qualify to graduate, said school officials told them it wouldn’t be fair to have just a handful of students walk across the stage.

Another dozen students from the high school’s alternative program qualified to graduate, according to KWTX.

As of Thursday morning, it appears the number of students eligible to graduate has risen to 17.
