Highest-leverage developer skills to learn
If you only have time to learn a few things, learn these. Each skill below is scored on three things at once: how often employers ask for it, what it pays over a typical developer role, and how often people actually pass it when they practise. The skills that are in demand, pay well, and trip people up are the ones worth your study time — they sit at the top.

Pass rate is the share of correct answers among people who practised that skill on CodePrep — a self-selected group, not every developer — so read it as relative difficulty, not a universal stat. It comes from how people actually scored, not what anyone claimed. Leverage scores demand, pay, and difficulty together (out of 100); a higher score means a skill is both worth learning and worth your study time.

These are skills named in recent job posts on the boards we track that don't yet match a topic on CodePrep — so the count is mentions across our tracked, ingested postings, not the whole market. We list them as an early read on what's rising, not a measure of adoption. Trend compares the most recent three months with the three before.
