At the secondary school level, teaching assistants often specialize in a certain subject, such as math or science. Assistants often take charge of special projects and prepare equipment or exhibits, such as for a science demonstration. Some assistants work in computer laboratories, assisting students using computers and educational software programs. In addition to instructing, assisting, and supervising students, teaching assistants grade tests and papers, check homework, keep health and attendance records, type, file, and duplicate materials. They also may stock supplies, operate audiovisual equipment, and keep classroom equipment in order.
Many teaching assistants work extensively with special education students.
Schools are becoming more inclusive, integrating special education students into general education classrooms. As a result, teaching assistants in general education and special education classrooms increasingly assist students with disabilities. Aides may attend to a student's physical needs, including feeding, teaching good grooming habits, or assisting students riding the school bus. They also may provide personal attention to students with other special needs, such as those whose families live in poverty, or students who speak English as a second language or need remedial education. Assistants help assess a student's progress by observing performance and recording relevant data.
