Expert TA is an educational software company that has tackled the never before solved problem of partial credit grading of complex equations, such as those found in engineering. The company will provide a Software as a Service (SaaS) homework assessment tool to engineering, physics, and math departments at colleges and universities. College students submit a large amount of homework, and that work must be evaluated. While departments in the humanities and social science area have strongly adopted online assessment systems, technical fields such as engineering have not, due to lacking grading capabilities.
