Considering that neuro-linguistic programming (NLP) is a vital approach to foreign language teaching, this study aims to explore the correlation between NLP and other factors that can influence this domain, namely, second language willingness to communicate (L2WTC), sensory motivation, and foreign language achievement. Adopting a quantitative design, 199 Iraqi EFL learners from intermediate to advanced proficiency levels were recruited to complete a newly developed NLP-Student Version Scale (NLP-SVS) along with the L2WTC scale and the active/passive motivation scale (APMS). The results confirmed the psychometric validity of the NLP-SVS. Moreover, the findings demonstrated a significant correlation among NLP-SVS, APMS, and L2WTC. Likewise, L2WTC significantly correlated with NLP and APM. Furthermore, NLP proved to predict foreign language achievement when mediated by sensory motivation (active and passive subconstructs). The results indicated that NLP, mediated by active/passive motivation, is a positive predictor of L2WTC. Lastly, implications and suggestions for further research were offered.
