When most people picture coding, they imagine lines of text on a screen. But the foundations of coding don't start on a computer. They start with how you think.
That’s the premise of Code Without Computers, a Cognizant Outreach program where our associate volunteers teach coding to school kids using simple blocks and play cards. This gives children in India foundational skills that support their future success, without the need for computers or internet access.
Code Without Computers began in 2023 with 10 schools.
The coursework spans 20 sessions. The first 15 cover core programming blocks—event, motion, control, sound and looks—the same categories any new programmer learns. The final five focus on AI: how data works, natural language processing, computer vision, AI ethics and generative AI.
Each session is led by Cognizant volunteers, who complete a train-the-trainer program before stepping into the classroom. Some even arrive with no coding background of their own.
Since launching in 2023, the program has reached more than 2,500 students across 50 schools, supported by 1,000+ Cognizant volunteers. And it's still growing: this year, we're expanding the program for students to deepen their skills, ending in a hackathon open to students nationwide.
Nitin Khemka, Senior Process Executive and volunteer
I’ve taught around 20 classes now and I still watch for the same moment in the first session.
A table is covered in blocks. In front of it sits a room of students who have never heard the word algorithm. They pick up the instructions and start arranging them in an order that makes sense to them.
When it doesn't work, the mistake lies on the desk in front of them. Nothing crashes. Nothing needs restarting. They shift one block, read the sequence again, and try it once more.
That's what removes the fear. Coding has a reputation among children for being difficult long before they attempt it, but a single session with the blocks dismantles it.
Deepali, Student at MJP Indresham
Code Without Computers helped me improve my logical thinking, creativity and confidence. It was fun. It also meant less screen time.
We used the blocks to make games. I showed mine at home and had to explain how it worked, step by step, because nobody there had seen anything like it before.
Sai Divya, Teacher at MPJ Indresham
Sai Divya says her students always had the talent. What they didn't have was anyone to draw it out. Cognizant's volunteers sparked their curiosity and gave it direction.
That’s what happens when 1,000 volunteers keep showing up: not just 2,500 children who can code, but 2,500 children who now know what they're capable of.
