Our School Programs

The infant program at Building Kidz School

Infant Program

In this class we brighten up the world by helping our youngest children discover their senses, explore their surroundings, nurture their development and celebrate their milestones. From one-on-one interactions that help build nurturing relationships in everyday moments to age-appropriate books to support speech and language development, our classrooms provide the ideal setting for the youngest children. We are also encouraging children to work on finger painting, music, and pretend play to spark creativity while also exposing them to structures to help with perceptual motor development. When children leave this classroom they will have a Brighter Beginning to the world around them.

The toddler program at Building Kidz School

Toddler Program

Our classroom provides an ideal environment to foster individual development and self-help skills. We use a scaffolded approach to learning through systematically building on students’ experiences and knowledge as they are acquiring new skills in order to enhance learning and aid in the mastery of tasks. Their curious minds are exposed to an enriched curriculum focusing on language development by using pictures, books and basic academics in their environment. Following simple instructions is implemented through circle time, story time, art, and curriculum projects. Besides the social, emotional development, we also focus on developing fine motor skills through fun and sensory activities. Our Little Explorers are ready to put to practice their newfound independence by exploring their surroundings as they come with a Brighter understanding of their world around them.

Parent Testimonials

My son Tyson has gone to Building Kidz since he was 10 months old and is now a bit over 4 years old. I really liked our teachers over the years, especially Ms Mary and Ms Rosa, who have both looked after him and genuinely care about his growth and development. Ms. Mary has been especially helpful in this past year; she is a trusted resource towards my son's development (as he is neuro atypical/with ASD). I felt comfortable leaving him at Building Kidz while I worked full time. One of my favorite things that they've implemented is the use of an app that allows me to see hourly pictures and videos of my son while I'm at work. It's very reassuring to see what activities my son is doing, what meals and snacks he's gotten, and how his naptime has been for a fairly anxious first time mom like myself. I also loved that there is some curriculum and structured activities every day to promote learning or has a holiday theme. During the summer sometimes they will have bounce house days, inflatable pool days, and BBQs for the kids. Their playground area is very large-there is an area for each age and classroom. I also like that they incorporate music lessons, art time, dance teachers, and theater into the weekly schedule.
I'm impressed with how well they have been able to handle the school during the pandemic. They always take my son's temperature at the door and parent can use the app to attest to a lack of symptoms before drop off. The director, Karen, always has a friendly, welcoming face.
My son has had a lot of lovely memories at Building Kidz and has made friends here over the years. I would definitely recommend this school to other parents.

I may be in the "honeymoon phase", but I so far LOVE this school. My child is only starting week 2 in the toddler room, and we couldn't be happier. This is the third day care we have enrolled in, and I finally feel like we found the perfect place! The teachers put the kids first. They are prepared, on a good routine, knowledgeable and confident. It helps give me (first time mom) piece of mind that my baby is being well taken care of in a safe, clean, social environment. And the brightwheel app is AMAZING - I get an update almost every hour with pictures throughout the day. I will try updating this review in a few months when we get more established, but for the first time, I finally feel truly comfortable and okay with leaving my child at day care. Thank you.

Update: we have been at Building Kidz for almost 3 months now, and we still love it. I can't say enough about the teachers in the infant/toddler room - they are absolutely amazing! The place is cleaned nightly by a cleaning crew, and I always see the teachers cleaning as well - so the cleanliness and sanitation is top notch. We are so happy to have found Building Kidz - we hope to have another little one in the next few years, and I already know where his/her daycare will be!!
Thanks again, Building Kidz. You ROCK!

Ah Building Kidz. You deserve 10 stars and beyond. I didn't know how much I really appreciated the school, the staff, and the curriculum. Recently planning to move, so I toured about 5-6 schools in the east bay, mainly in Castro Valley and Hayward area. And base on their Yelp reviews (4.5 stars to 5 stars), you would assume the school can be comparable. Oh man I was totally wrong. I have not seen ONE school as good as Building Kidz. Seriously.

Academic achievement is HUGE in our family. I knew the multiplication table in kindergarten, can do two digit division in first grade. Ok let's stop bragging about me. So you get the pic. I want my daughter to be as smart if not smarter. She is currently 3 years and 3 months. She knows her alphabets, when I say know her alphabets I'm not saying just singing the ABC song, she can spell out street names and signs in front of the stores. She can count to 20 with no problem. All colors and shapes. Vocabularies are amazing. Really. When we toured other schools recently, they all said my daughter is very advanced and could even go with the 4 years old class.

The school itself is amazing! Every age group has their separate classroom with windows and doors. Not just separated by a book case or toy shelf, I'm talking about real, legit rooms. New both babies have their own crib for nap. Completely separate from the preschool side. And they take kids as young as 6 weeks!!! OMG! Their playground/ yard is HUGE. When I toured other schools, I wasn't impressed by any of the playground. We've been spoiled here :(

My daughters been coming since 1 year old. They potty trained her for me after she turned 2. Yes it was very easy and quick. I think 2-3 months? Going from full diaper to full potty trained. No BS.

Another BIG comparison is their curriculum. They are big on art projects. Every semester my daughter has these 3 inch binders full of her art work. They have outside teachers who come in and teach dance and music class (free) which they have a big performance for every year. Spanish class (free), I think they will start French this fall. For sports class like gymnastic and soccer, they come once a week but parents will have to pay a little extra so it's optional, which I don't mind at all. These schools I toured recently don't have music and and art :( very sad and most of them don't bring in outsider to teach gymnastic and soccer, even sadder :( :(

Their tuition include breakfast, lunch and 2-3 snacks a day! Omg where can I freaking find a school like this? Why can't you just open another one in Castro Valley area? They are in high demand! So sad we're moving. And we've been dragging it out since we can't find any good schools :( we're going to be so sad when we leave... :'( Sigh....

I had posted a review last year when my son started at this school, but I feel like I have to write again about how happy I am to send my son to this school specially with Covid time! I couldn't trust to put my son in a school due to Covid, but I'm very happy with this school's protocol . They are very clean and they make sure to check kids temperature before they enter the school, they spray their hands and sole of the shoe with sanitizer. Teachers make sure to keep kids masks on to keep everyone safe. They had asked me to show negative Covid results once kids came back from Christmas break which I thought was great! I felt relieved I didn't have to worry about kids coming back sick after a long break. The director Karen is Awesome!! Very professional and friendly! The owner sangita Hingorani is great and very understanding! I met all the teachers there and they are amazing! My son has learned so much the last year! I encourage every parent to check this school if they are looking for a child center for their kids. Very very very happy with it!

About Building Kidz of Concord

Are you wondering where the best preschool or childcare in Concord is? With a campus that boasts three large play yards, plus a separate yard just for toddlers, the answer is clearly Building Kidz of Concord.

How are preschools reacting to the California wildfires? At Building Kidz of Concord, not only have we installed “Molekule” air purifiers in each of our classrooms, we have also added “Purple Air” air quality monitors, allowing us to monitor airborne particulate matter, both indoors and out.

Our enhanced security measures, including video cameras throughout our classrooms and playgrounds, touch pad entry, and advanced parent communication provided by Brightwheel, allow you to rest assured that your child is safe all day. If you are looking for a locally owned, community child care center that takes safety, security, and cleanliness seriously, look no further.

Our curriculum is a comprehensive arts-integrated learning program in which children develop skills and knowledge of math, literacy, music, arts, socialization, self-regulation and control, morality, fine and gross motor skills, and emotional expression – all while having fun!

Our curriculum is delivered by top-rate preschool teachers and committed support staff that has been dedicated to the Building Kidz of Concord mission for many years. They and we will continually strive to deliver unparalleled care and curriculum to local families and children.

Our performing arts integration includes two shows annually; Building Kidz of Concord students participate in a Broadway-style production in June and a winter recital in December.

Our mission is to deliver a world-class infant care, childcare, and preschool experience which results in children developing a deep passion for learning and connecting with the performing arts, while also demonstrating accelerated development of their confidence, commitment, and character.

Our philosophy is to develop the “whole child”. We focus on 6 key areas of development: emotional, social, cognitive, physical, communication, and academic. We create an environment where children are challenged intellectually and are engaged in an interest of lifelong learning through an intelligent integration of academics and performing arts.

Building Kidz of Concord is part of the Building Kidz Worldwide family of campuses, providing kindergarten, preschool and childcare services to local area families. We are located at 5100 Clayton Road in the Vineyard Shopping Center and conveniently close to Ygnacio Valley Road.

Our philosophy, our arts-integrated curriculum for infants, toddlers, preschoolers and kindergarten children, and our commitment to our community and its families have made Building Kidz of Concord one of the top preschools and kindergartens in Concord.
