Oregon legislative leaders say they will move forward this week with a K-12 school budget education interests call inadequate.  House Speaker Tina Kotek and Senate President Peter Courtney, both Democrats, say school districts need certainty as they develop their budgets, and they say if the May revenue forecast shows the state can expect more money, 40 percent would go to K-12 schools.  But Republican Senate Minority Leader Ted Ferrioli says it is unlikely the revenue forecast would jump by the over 600 million dollars needed to move the K-12 budget to the seven-point-five billion dollars education advocates say is the minimum needed.  The Ways and Means Subcommittee passed the education budget today on a partisan vote.
