(AP) - Plans are still moving ahead to consolidate Connecticut's 12 community colleges into one accredited school by 2023.

That's despite stepped-up opposition from faculty unions.

They say there are too many unanswered questions and concerns about the complex undertaking. It's an idea that's been around since 2017.

Connecticut State Colleges and Universities President Mark Ojakian expressed confidence the regional college accreditation organization will be impressed with the latest transition report that's due in late April.

But four CSCU unions recently issued a joint statement in opposition to the proposal, arguing there are many unanswered questions and questioning whether it makes sense.
