CHARLOTTE, N.C. — Families at South Academy of International Languages are asking Charlotte-Mecklenburg Schools for more information about a proposal to move the magnet school’s start and dismissal times one hour later next school year. The school currently runs from 8:15 a.m. to 3:15 p.m. Parents say traffic is already backed up at dismissal, with some drivers waiting to enter because the parking lot cannot accommodate all car riders at once. “That creates a compounded traffic effect,” said Linda Schaffluetzel, president of the school’s Parent Teacher Student Organization. She said the congestion is already an issue at the current 3:15 p.m. dismissal. Parents said they learned of the proposed shift at the same school board meeting where Superintendent Crystal Hill was terminated. They say their emails to board members have not yielded much information about how the recommendation was developed. The schedule change could also affect enrollment, families argue. SAIL’s language-immersion program begins in kindergarten, so students cannot join the program in later grades. Parents worry that if current students leave, the school may not be able to replace them with transfers, potentially putting enrollment — and the program’s future — at risk. Parents shared results from a survey of 400 people connected to the school; nearly half said they would not return if the schedule changes, according to the parent group. Parent Karly Wood said families should not have to leave a school over a time change they feel was made without considering their needs. Parents plan to meet with the district’s transportation chief on Monday, Oct. 12, and said 20 to 30 people expect to attend the school board meeting Tuesday, Oct. 13. Schaffluetzel said families are seeking additional data and an explanation of how the district reached its recommendation. Charlotte-Mecklenburg Schools had not responded to a request for comment as of Sunday, Oct. 11.
