Computer Science Achievement and Writing Skills Predict Vibe Coding Proficiency

A preregistered study of 100 tertiary-level students found that computer science achievement and writing skills are significant predictors of proficiency in LLM-driven 'vibe coding', with CS achievement remaining significant after controlling for domain-general cognitive skills. The study, submitted to arXiv on 14 Mar 2026, used tasks curated by eight experts and a purpose-built environment mirroring commercial tools, informing tool and curriculum design.

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 remains a significant predictor after controlling for domain-general cognitive skills. The results may inform tool and curriculum design, including when to emphasize prompt-writing versus CS fundamentals to support future software creators.
