Norwich — Norwich Free Academy will undergo a major restructuring with staff cuts, redefined positions and operations changes in the 2021-22 school year based on sharply declining enrollment, uncertainty in international students and continuing costs of COVID-19 protections. But while the overall operating budget of $34.6 million — approved by the school's board of trustees Tuesday — will decrease by $3.2 million, or 8.46%, from this year’s $37.8 million total, tuition for the eight partner districts with NFA as their main designated high school will increase by 3%. Regular education tuition will be $13,175 for Norwich and $13,375 for the seven other districts. Norwich receives a discount of $200 per student for host-town services.
