• An F5 tornado is the strongest tornado recorded. Here at Sulphur 9th Grade, we would like to acknowledge our freshmen students that display strong character, academics and school involvement. The student must maintain an overall grade point average of 2.5, no discipline referrals and a minimum of 2 activities/sports/clubs. Our partner in education, Citgo, rewards F5 students with a pizza party and a t-shirt that may be worn any day of the week. For questions, please contact Chuck Hansen or Dielle Barrentine.
