It is very common for high schools to offer night classes, although availability depends on the school district. The school district's website usually lists information about evening high school class availability, requirements and locations.
For instance, as of 2015, the Anne Arundel County Public Schools district in Maryland offers several campuses with night classes, while the Kearny School District in New Jersey reserves one high school to offer the night classes. Requirements for attendance may include being under a certain age and paying a fee.
Night classes can be beneficial for people who are missing some credits for graduation or who have quit school in the past.
