Teachers also won concessions on planning periods. Tomblin's original bill would have cut planning periods to 30 minutes. Instead, teachers will get a minimum of 40 minutes of planning time each day.
The initial bill proposed changing state law so county school boards could offer a "balanced" or year-round calendar. State law now limits the school calendar to 43 weeks.
Tomblin's revised bill increases the yearly school calendar to 48 weeks.
The bill eliminates days that school boards could count as instructional days, even though students weren't in school. The changes give county school systems more flexibility to make up snow days.
"You have to get 180 full days of instruction in," said Senate Education Committee Chairman Robert Plymale, D-Wayne. "This is a huge step to ensure our kids are getting adequate time in the classroom."
Sen. Mitch Carmichael, who voted for Tomblin's bill Monday, said the governor's proposals "take steps in the right direction."
But Carmichael said the legislation doesn't give enough authority to county school boards -- a recommendation detailed in an education efficiency audit released last year.
"We have missed a golden opportunity," Carmichael said. "We need fundamental, aggressive reform. Instead, we have taken the soft option."
Dale Lee, president of the West Virginia Education Association, said teachers called and sent thousands of emails to state lawmakers in recent days, prompting the "compromise" bill.
"This would not have happened if teachers had not been outraged and had their voices heard," Lee said.
Tomblin's revised bill kept several proposals:
• State law would no longer require state schools superintendents to hold a master's in education administration. The bill's supporters say the change would increase the pool of applicants for the superintendent's post.
• Elementary school teachers would receive specialized training designed to increase the number of third-graders who end that year reading at grade level.
• Full-day pre-kindergarten programs would be available to 4-year-olds statewide.
