The Ridgefield Public School District is considering an audit of school security in the wake of the elementary school shooting in Texas.  The Board of Education discussed a possible launch of the more formal review during an executive session last week.  An audit could bring in experts to help identify where there are strengths and opportunities for growth.  Superintendent Susie Da Silva says the discussions are preliminary and nothing has been ruled out at this point.  During the Board meeting Monday, Da Silva said approved projects that have been delayed due to increasing costs could be put back on the table such as a vestibule at an elementary school.  The Board previously asked the Board of Finance to put any surplus finding toward an account for school playground upgrades, but will instead ask that the money be put toward security projects.
