Leaders in some school districts are placing limits on when -- and how often -- parents can check online grade portals, writes teacher and author Jessica Lahey. In a commentary in The New York Times, she shares the potential downside of parents "overchecking" grade portals, writing that in high-pressure school districts, parents will view the district’s invitation to constantly monitor grades and scores on the portal not as an option, but as an obligation. This obligation adds to the mounting anxiety students and parents feel in these districts.
