A process diagram. The three cores are student, tutor and ETMA system. The process shows the TMA going from the student to the ETMA system and then the TMA going from the ETMA system to the tutor together with a blank assignment summary. It returns from the tutor back to the ETMA system as a marked TMA and a completed assignment summary. The marked TMA and completed assignment summary then go from the ETMA system back to the student.
