The VIT defines 7.6 hours as equivalent to a day of teaching.
If you are employed as a teacher for a full day (ongoing, contract or casual), you can consider this a day of teaching.
If you are employed for half a day as teacher, regardless of face-to-face teaching time, VIT will consider this half a day of teaching.
Teaching hours include your face-to-face teaching time, as well as the time you spend preparing the learning environment and assessing learner’s work.
