Computer Science Achievement and Writing Skills Predict Vibe Coding Proficiency
Sverrir Thorgeirsson, Theo B. Weidmann, Zhendong Su

TL;DR
This study identifies computer science achievement and writing skills as key predictors of success in vibe coding, a natural language programming approach supported by large language models, based on a controlled experiment with students.
Contribution
It provides empirical evidence that CS achievement and writing skills significantly predict vibe coding proficiency, informing educational strategies and tool development.
Findings
CS achievement predicts vibe coding success
Writing skills are a significant predictor
CS achievement remains significant after controlling for cognitive skills
Abstract
Many software development platforms now support LLM-driven programming, or "vibe coding", a technique that allows one to specify programs in natural language and iterate from observed behavior, all without directly editing source code. While its adoption is accelerating, little is known about which skills best predict success in this workflow. We report a preregistered cross-sectional study with tertiary-level students (N = 100) who completed measures of computer-science achievement, domain-general cognitive skills, written-communication proficiency, and a vibe-coding assessment. Tasks were curated via an eight-expert consensus process and executed in a purpose-built, vibe-coding environment that mirrors commercial tools while enabling controlled evaluation. We find that both writing skill and CS achievement are significant predictors of vibe-coding performance, and that CS achievement…
