A bill to make the Connecticut Technical High School System into an independent executive-branch agency has been approved by the House and awaits Senate action. The 17-school system, which includes Henry Abbott in Danbury, would be lead by someone appointed by the governor and approved by the General Assembly. That person would oversee the superintendent. The system's former superintendent, Nivea Torres, quit in April amid an investigation into $4.5 million in taxpayer-funded contracts with a marketing firm. They were for promotional services, including writing her tweets.
