Why STEM Literacy Is the Third Core Literacy

Reading and math are non-negotiable. So is the ability to think like a scientist, engineer, and creator. STEM literacy — defined as the 4Cs+2Ps — is the set of capabilities that makes humans irreplaceable in the age of AI.

AI can recall facts, follow procedures, and calculate at superhuman speed. What it cannot do is find problems worth solving, create something genuinely new, think critically about its own output, communicate with empathy, collaborate across difference, or solve problems that have never been seen before.

Those six capabilities — Creativity, Critical Thinking, Communication, Collaboration, Problem-Finding, and Problem-Solving — are the 4Cs+2Ps. Together, they form STEM literacy: the third core literacy every student needs, alongside reading and math, to thrive in a world shaped by intelligent machines.
