A teachers union has reached an agreement with the state's Ethics Commission on new guidelines for teachers who receive free travel to serve as chaperones on school-related trips.
    
The Hawaii State Teachers Association, which represents 13,500 teachers, announced Tuesday it had worked out a resolution to the long-standing dispute over the matter.
    
Under the agreement, teachers will still be allowed to plan trips and serve as chaperones with private tour companies, which typically allow one chaperone to travel at no cost for every eight or 10 students who pay for the trip.
    
But teachers who travel for free are now required to inform students and their families that their travel costs are being paid for. They also are prohibited from accepting any personal perks for the leading the trip, such as tablet computers.
