Nia Smith says, for her family, public schools weren’t working. Her son has special needs, and she wanted to put him in a small school with a strong sense of community and specialized instruction. But, with her budget, most of the major private options were out of reach. With a state school voucher — an Opportunity Scholarship — she was able to afford to enroll her son last year at ALC Mosaic, a secular private school in east Charlotte.
