The Maryvale School Board Monday received an update on 13 students who failed to graduate between 1994 and 1996.
Four of the 13 retuned to school and earned their diplomas; two earned a general equivalency diploma; two are currently enrolled in school; and the remaining five have not returned to school.
School Superintendent Gary Brader said the students averaged 32.8 absences and were late 13.2 times.
"One student was absent 63 days; another was absent 93 days," Brader said. "When you miss that much school, you're not going to graduate."
Brader said district enrollment has increased slightly since last May, to 2,521 from 2,454. The pupil-to-teacher ratio in kindergarten through sixth grade, however, has dipped from 27.3-to-1 to 24.8-to-1.
In other business, Michael Freas, superintendent of buildings and grounds, told the board that sections of district roofs have been "blistering" due to moisture and ultraviolet rays.
"We're doing all we can do in terms of repair work," Freas said.
Some of the roofing was installed in 1963, and much was installed in 1980.
"People expect roofing to last longer than 16 years," Freas said. "That's not the case with flat roofs, which is what we have."
Brader said the board will monitor the situation closely and may consider a bond issue in the future.
