The last bell of the school year has sounded for most LaSalle Parish public school students. Homework is done. The buses are parked and ready for summer maintenance and repairs. The lunchrooms are vacant and the playgrounds are still. This year of learning is, in a sense, one for the books. However, in just a few days or maybe a few weeks the parking lots of the various schools across the parish will begin to be spattered with cars, SUVs and the like of the 198 educators that fill the pre-k through 12th grade teaching positions in the LPSB district.
