Schedules present obstacles to learning, including year-round schedules that result in a reduced number of instruction days. Some schools lack adequate heating, ventilation, or air conditioning. In some schools, classrooms are created in spaces previously used as gymnasiums, libraries, and auditoriums. Some teachers have not yet obtained teaching credentials. Roaches and vermin inhabit some classrooms.
Some schools offer too few courses.
Some schools have filthy bathrooms and toilets with no seat covers. Some classrooms don't have enough seats for students. In some schools, libraries are closed. The supply of paper and pencils is insufficient in some schools. Those problems occur disproportionately in schools serving minority students in urban areas.
