Warren County Schools had its supplemental student-athlete insurance and substitute teachers approved on Monday, but the brakes are still on its bus service.“We had two bids come in on our insurance,” said Director of Schools Bobby Cox before members of the county Financial Management Committee.Prince Insurance Agency submitted an annual premium bid of $15,025 with maximum benefit of $25,000, while Scholastic Insurors Inc. submitted an annual premium bid of $13,980 with a maximum benefit of $10,000.“We’ve used Scholastic in the past,” said Cox. “We would like to stay with them. Prince is a little bit more than we wanted to pay, even though their maximum benefit was a little bit more.
