Students with disabilities who are not included are typically either mainstreamed or segregated.
A mainstreamed student attends some general education classes, typically for less than half the day, and often for less academically rigorous classes. For example, a young student with significant intellectual disabilities might be mainstreamed for physical education classes, art classes and storybook time, but spend reading and mathematics classes with other students that have similar disabilities. They may have access to a resource room for remediation of course content.
A segregated student attends no classes with non-disabled students. He or she might attend a special school that only enrolls other students with disabilities, or might be placed in a dedicated, self-contained classroom in a school that also enrolls general education students.
Some students may be confined to a hospital due to a medical condition and are thus eligible for tutoring services provided by a school district. Less common alternatives include homeschooling and, particularly in developing countries, exclusion from education.
