Seniors at Danvers High School will be getting a hands-on lesson in budgeting at the school’s eight annual Reality Check Fair from 9 a.m. to 1 p.m. at North Shore Community College’s Danvers campus. The fair is an interactive, four-hour exercise aimed at preparing graduating students for the demands of balancing their income and expenses and making financial decisions that will affect their future. The 230 students taking part in the exercise will each be given a fabricated credit history, a job and salary fact sheet, and a set of everyday financial tools. Students will be asked to manage their money for one month, working within the salary and credit history provided, and make decisions about housing, health care, food, and entertainment. Along the way, they will run into unexpected real-life situations that will either improve or worsen their financial situation for that month. People’s United Bank is the lead organizer of the program, working closely with faculty and administration at the school, along with representatives from the Federal Deposit Insurance Corporation and MassHousing.
