Early Childhood Education at Mountainside Campus

The Holy Trinity School Mountainside Campus provides our youngest students with an age-appropriate, faith-based, academic program supporting the whole child while fostering a sense of community for the entire family.  Family masses are held on Holy Days, and students participate in monthly para-liturgies in the church led by priests from our Our Lady of Lourdes, Holy Trinity, and St. Helen’s Church.

The educational needs of the students are met through a curriculum devised to provide quality education for the young child in a developmentally-appropriate and nurturing Catholic environment.  Teachers focus on developing the individual strengths of each child, while simultaneously developing the skills necessary for a successful transition to the elementary years at Holy Trinity School at our Westfield campus.

PreK-4 Plus, PreK-4, PreK-3, and 2 Year Olds

Students as young as two years old begin to develop a life-long love of learning in a classroom that is staffed with a certified teacher and an aide. The Pre K curriculum from PreK 3 through PreK 3 + emphasizes language development, reading and math readiness skills, art awareness, social development, and follows the tenets of the Catholic Church.

PreK 4 and PreK 4+ continue with the curriculum put forth by the Archdiocese of Newark and it includes experiential learning with a balanced approach  of center based learning combined with a strong emphasis on reading and math readiness skills. Children in our program receive weekly special instruction in music, library, creative movement, and Spanish.

Both indoor and outdoor play are an integral part of the curriculum for our Early Childhood Program.  The campus offers a safe, well-equipped and maintained outdoor play space, as well as green space for outdoor games and exercise.  On rainy days we utilize our newly refurbished auditorium/gym area to promote physical exercise and cooperative play.





Full-Day Kindergarten (offered at both Mountainside & Westfield Campuses)

The philosophy of our kindergarten program at Holy Trinity is to provide an opportunity for each child to grow and develop through his or her achievement in religion, reading, and math.  We believe in the importance of helping each child build a good self-image and develop his or her own sense of worth in the world.  Stages of development can be enriched, but not accelerated.  Although the children are entering kindergarten at various levels of development, we are proud to accommodate all students in our full day, academic kindergarten program.

Our program offers activities intended to enhance listening skills, pre-reading and reading skills, math skills, and awareness of our Catholic faith.  Our learning program includes:

  • Art projects using a variety of tactile materials
  • Print capital and lowercase letters
  • Number concepts 0 – 20
  • Counting 1 – 100
  • Opposites; rhyming words
  • Speaking and communication skills
  • Relationships of objects (color, size, shape, position)
  • Addition and subtraction
  • Recognize beginning & final letter sounds and medial vowel sounds
  • Address, telephone number, birthday
  • Day of the week, months, special holidays
  • Science concepts
  • Social studies topics
  • Speaking and communication skills
  • Special classes weekly in art, music, library, and Spanish

It is hoped that students beginning their learning at the Mountainside Campus continue their education through the grades at the Westfield Campus, embarking on an educational journey in the tradition of the Catholic School system that has served Westfield and the surrounding communities for over 100 years.
