From 2015, CBSE schools may have 6 functioning days

CBSE schools may function for six days a week from 2015 at the secondary and senior secondary levels.
The board is mulling extending the functioning days keeping with the mandate of the Right to Education Act which seeks to fulfill 45 working hour per week.
"In order to complete the 45 working hour per week as per the recommendation of RTE-Act 2009, a school needs to function for six days a week for 6 hours and 10 minutes on each day," CBSE said in a school curriculum published for 2015.
It further suggested that teachers may be retained after school hours for an additional hour and 20 minutes which can be used for planning, preparation, checking and follow up work.

The teachers shall devote in a year not less than 1200 hours to the actual teaching in classroom in classes I-VIII, out of which not more than 200 hours may be required for remedial teaching and attention to both weak and gifted students before or after the school hours.
It also said that if any teacher is required to devote more than 1200 hours to the teaching and planning, extra remuneration shall be paid at such rate as may be determined, by the managing committee for every hour in excess of 1200 hours devoted by her to the teaching and planning.

All teachers are required to teach for a minimum of 30 periods per week with remaining periods to be used for planning and preparation of the lessons and activities.
Eight periods time table may be followed in schools with 45 minutes duration in the 1st and 5th periods and 40 minutes duration for the remaining periods.
