21. Now I would like to ask about information on the teaching experience of all the teachers directly involved in teaching. How many have teaching experience...
C. of 10 or more years?
Ask the number of teachers directly involved in teaching by the years of
seniority in teaching. Seniority here should be calculated according to the cumulative
number of years of direct teaching. Don’t include gaps when no direct teaching was done.
The total of column 3 A,B,C should be equal to the total number of teachers in question
