Python
Python is the best language to start with. It’s the most popular programming
language, and useful for every kind of programming.
This foundational course introduces students in grades 4-12 to the Python
programming language for the first time.
Students solidify core programming concepts including variables, functions,
loops, conditionals, and object-oriented design while earning globally
recognized credentials.
Students expand beyond syntax to learn event handling, game physics, and
software architecture by producing complete, playable games.
Students explore computational science by modelling gravity, planetary motion,
and physics-based scenarios in Python.
Java
For students of all levels who want to learn industry-level Java programming.
Students review League curriculum alongside official College Board materials,
including authentic practice questions from previous AP exams.
Students progress from introductory syntax to advanced object-oriented
programming, data structures, and algorithms using industry-standard tools.
Technology
We have many other technology classes involving AI, games, and robotics.
Students prototype ethical AI experiences while training models, generating
media, and deploying their own assistants.

Community Programs
Free and low-cost programs that bring computer science education to underserved
communities, with new classes every week.
A free, application-based League Labs clinic where student teams work with
professional engineers to plan, build, and ship high-quality software using
Claude Code and a rigorous engineering process.
Students experiment with LEDs, sensors, and radio communications to see how code
controls physical hardware.
Two High Tech High students worked with LEAGUE instructors to review the
Introduction to Python class, fixing spelling errors and making programmatic
improvements to the course material.
Students explored classic sorting algorithms, created video demonstrations using
physical cards, and collaboratively built a web application that visualizes
sorting and searching in action.
Students work as the first cohort of the AI Project Clinic, using Claude Code
and professional engineering processes to plan, build, and ship real software
projects with mentor guidance.
This foundational course introduces students in grades 4-12 to the Python
programming language for the first time.
Students learn game design and programming logic using Microsoft’s visual
programming platform with options to transition into JavaScript.
Students dive into the electrical and software principles behind motor control,
including PWM techniques for speed and direction.
Robot Garage Apprentices work closely with instructors on their own builds while
helping us explore what projects and lessons work best for future students.
