Several school districts in southwest Washington, including Vancouver and Evergreen, have delayed the start of the school year this week as teachers unions and districts failed to reach agreements over teacher pay.

The Columbian reports that districts and unions in Clark County and across the state are negotiating new pay scales due to new school funding legislation. The Legislature this year added nearly another $1 billion for teacher salaries.

School was canceled Tuesday for about 27,000 students in Evergreen Public Schools and 3,200 students in the Washougal School District.

Classes also won't start as scheduled Wednesday for 24,000 students in Vancouver School District and 6,500 students in Longview Public Schools as teachers hit the picket lines.

Teachers in Seattle, the state's largest school district, are scheduled to vote Tuesday on whether to authorize a strike after failing to reach an agreement with the district. School resumes Sept. 5 in Seattle.
