Wicked Local Frank Hackett is still the choice to replace Judy Evans as Winchester superintendent when she retires in June, but details on his contract are still being worked out. The Winchester School Committee was scheduled to vote during its March 2 meeting on the contract, but School Committee Chair Brian Vernaglia said there's more to do. "We have an agreement in principle but the full contract is long and we are making sure both parties are comfortable with all the legal terms," he said. "We hope to be able to vote at our next meeting if not sooner, at a special meeting if necessary."
