5 Pillars of the Castillo STEM Academy’s Educational Model

The Leonel Castillo Early Childhood STEM Academy distinguishes itself by focusing on a holistic, forward-thinking curriculum designed specifically for young learners in Pre-K (PK3 and PK4) and Kindergarten.

1. High-Impact Early STEM Immersion

Unlike traditional pre-K programs that may only touch upon science, the Castillo Academy places a robust emphasis on STEM instruction. The curriculum is state-certified in literacy and math, but it is deeply integrated with a hands-on, inquiry-based STEM focus. This means that children are not just memorizing facts; they are actively engaging in problem-solving, experimentation, and critical thinking. The goal is to nurture natural curiosity and build a strong foundation in the core disciplines of Science, Technology, Engineering, and Mathematics.

The Raul Yzaguirre Schools For Success (RYSS) district, which oversees the Academy, demonstrates its commitment to this model through participation in related programs like Children Investigating Science with Parents and Afterschool (CHISPA) at its other campuses, reinforcing a district-wide culture of scientific exploration.

2. Foundational Literacy and Numeracy Skills

The Academy's curriculum is meticulously aligned to the Texas PK Guidelines, ensuring a strong base in essential academic areas. Key instructional areas include Emergent Reading and Emergent Writing, which are crucial for future academic success. By focusing on these emergent skills, the school ensures that students develop phonological awareness and early comprehension, setting them on a path to reading proficiency. The math curriculum is equally rigorous, preparing students with the numeracy skills needed to thrive in the STEM-heavy environment.

3. Comprehensive Social and Emotional Learning (SEL)

A high-quality early childhood education is incomplete without a focus on the whole child. The Castillo Academy implements a solid Social and Emotional Learning (SEL) program. This curriculum teaches young children vital life skills such as self-management, responsible decision-making, relationship skills, and social awareness. By fostering a nurturing and emotionally supportive environment, the Academy helps children develop the confidence and interpersonal skills necessary to navigate the classroom and the world beyond.

4. Holistic Development Across All Domains

The educational experience at the Leonel Castillo Academy is broad and balanced, covering all developmental domains. In addition to the core STEM and literacy subjects, the program includes robust instruction in Social Studies, Fine Arts, and Physical Development. The inclusion of Fine Arts ensures creativity and expression are nurtured, while Physical Development promotes healthy habits and motor skill refinement, all contributing to a well-rounded and engaged student.

5. Commitment to Closing Achievement Gaps

As a public charter school, the Academy is committed to serving its community and addressing educational inequities. The school's leadership is focused on executing a system that supports the implementation of the district curriculum to effectively close student achievement gaps. This targeted approach is crucial for the Near Northside area, providing students with a high-quality, specialized education that might otherwise be inaccessible. Furthermore, the Academy has a responsibility to proactively identify, locate, and evaluate students who may need special education services, ensuring every child receives the support they need to succeed.

The Impact of the Raul Yzaguirre Schools For Success (RYSS)

The Leonel Castillo Early Childhood STEM Academy is a key component of the Raul Yzaguirre Schools For Success (RYSS) network, which is dedicated to providing quality educational experiences to a diverse student population in Houston. RYSS operates various academies, including other STEM-focused campuses, demonstrating a strong, district-wide commitment to innovative and specialized education. This network provides the Castillo Academy with a supportive infrastructure and shared resources, ensuring the curriculum remains current, effective, and aligned with the latest educational research.

By operating out of the Leonel Castillo Community Center, the Academy further integrates itself into the fabric of the neighborhood, often facilitating community events like food distribution, which underscores its role as more than just a school—it is a vital community hub.

In conclusion, the Leonel Castillo Early Childhood STEM Academy is a model for 21st-century early education. By honoring the legacy of a great community leader and pioneering a rigorous, yet nurturing, STEM-focused curriculum, the Academy is not just teaching children; it is building the foundation for a future generation of innovators and successful global citizens in Houston, TX.
