It's a mixed bag for Thunder Bay's elementary schools. The Fraser Institute ranks half of them at above or at the provincial average; the other half falls below. Spokesperson Michael Thomas says the rankings alert officials that something needs to be done. Vance Chapman school saw it's rankings slide from already below the provincial average at 3.7 to 1.7. Claude E. Garton also saw their marks decline this year. St. Francis, St. Paul and St. Thomas Aquinas all scored marks higher than the provincial average.
