Students in Saskatoon's public schools will have to spend an extra 15 minutes a day in the classroom, starting this fall.

Saskatchewan's biggest school division says it will be adding 15 minutes to the school day this fall, to meet new provincial requirements.

Saskatoon's public school board said Wednesday the change will allow it to fulfil the province's requirement of 950 instructional hours per year.

Right now, the schools are at about 910 hours, so 40 hours will be added.

As far as where those extra 15 minutes will go, it will be up to the individual schools to decide in consultation with the school division, board spokeswoman Veronica Baker said.

Some schools might put the extra 15 at the end, some at the beginning. It's possible some schools might want to add three minutes apiece to their five periods, Baker said.

The board will also reduce the number of instructional days from the current 197 to 195 starting this fall. 

That change will allow vacation schedules and the post-Labour Day school start to proceed as planned, she said.

The school divison has about 22,000 students attending 43 schools, making it the province's largest.

The 2013-2015 school calendar includes a two-week Christmas vacation, a 10-day spring break, including Easter, and a five-day break in February that includes Family Day.

The board says it surveyed about 5,700 members of the school community and most preferred adding minutes to the day, rather than adding days and keeping the school day as is.
