UPDATE: Both sides talked until midnight. Still no tentative agreement to announce yet on Wednesday.

Both teachers and administrators in the Seattle School District are expected to announce a tentative contract agreement soon.

"We believe we have a tentative agreement," says Glenn Bafia, with the Seattle Education Association.

He says smaller groups from both bargaining teams will get together Tuesday to review contract language and proposals.

"If we see that we are both on the same page, we will announce a definite tentative agreement," Bafia says. They'd make that announcement in the afternoon. Neither side is releasing details of the possible contract deal.

Teachers are scheduled to vote on a contract Thursday. They'll also take a confidence/no confidence vote in Superintendent Maria Goodloe-Johnson

It will be interesting to see how they resolved the issue of evaluating teachers. Goodloe-Johnson has introduced a process that links a small part of a teacher's evaluation on how well students do on a test that measures academic progress at several points throughout the school year. Teachers say it's not fair to link their evaluation to students' test scores.

Tuesday is also "wear blue in solidarity" day for Seattle teachers who are reporting to their classrooms to get ready for the new school year, which starts September 8th.
