New Car Seat Law

Effective January 1, 2017, children under the age of 2 will be required to sit in a rear-facing car seat.

This new rule will not apply to children under the age of 2, who weigh 40+ pounds or are 40+ inches tall. 

Parking Lot and Pick Up Loop

Traffic Safety Update

The City of Brentwood has committed to adding a double yellow line on Farmington in order to show where cars should not pass while entering the school parking lot.  There have been too many near misses with people trying to pass while a car ahead of them is making a left turn into the parking lot. 

There will be more curbs painted red in order to avoid creating blind spots.  Also, the City has applied for a grant to get flashing signs to indicate pedestrian traffic near the school


Important reminders

               Please DO NOT drop off or pick up your child in the parking lot by the cross walk.

               You must park your car and walk them over if you are going to use the parking lot.

Look at our new Ball Walls

The incredible juniors from Liberty's Public Art and Design Academy (PADA), came out during their summer vacation to help Mary Casey Black Elementary students, coordinated by Sandy Chaput and Alisha Douglass, to paint the school's mascot on the handball walls.

The high school students showed the elementary students the process for creating a mural. Everyone is proud of the end result.

Go Owls and Lions!
