School Reviews

All three of my children attended LTHS and I couldn't be happier with our decision to send them there. The community at large is caring and really shows that they love their jobs - everyone from the Superintendent's office to the custodian! My kids received a great education and are thriving in their post-secondary education.

The school was ridiculously crowded when I attended, but that did not prevent me or any of my classmates from receiving a quality education and succeeding if we really wanted to. The teachers were top notch and the school's amenities were also excellent. Given the enrollment size, I could not imagine teachers doing a better job than they already were. Great teachers, great school spirit and great facilities!

This school is way too crowded to give kids a safe and educational learning environment. The halls are crowded, not even split schedules help.

As a result, House democrats have taken up the issue in a new bill that would ban all forms of corporal punishment nationwide.
