Background and Purpose: Self-efficacy is one of the aspects of human behaviours related to performance in social cognitive theory. It has been studied in social sciences, education, and languages. There are a variety of self-efficacy scales available in the English and French languages to test one’s self-belief in their ability to learn the target language. To date, no self-efficacy scale catered to the unique characteristics of Mandarin as a foreign or third language (MFL). The objective of this study is to give practical recommendations on creating valid self-efficacy instruments of MFL and making judgments on factor extraction, factor rotation, and factor labelling based on the foreign language literature.
 
 Methodology: This quantitative study gathered information through an administration of a survey. The multipart survey consists of the demographic information section and the MFL self-efficacy scales distributed to MFL learners in Malaysian public universities. Data were collected randomly from 614 participants studying MFL at three different levels. Items for MFL self-efficacy were examined using SPSS version 25.0 software.
 Findings: The final 13 MFL self-efficacy items were reduced to four factors with a total variance of 68.99%. The Promax rotation matrices revealed the presence of a simple four-factor structure, exhibiting the degree of strong factor loadings. The four factors were MFL Speaking, MFL Listening, MFL Reading, and MFL Writing.
 
 Contributions: This research provides valid self-efficacy scales for MFL learning. The skill-based Scale could contribute to MFL teaching literature in the Malaysian context. Additionally, the study proposes future investigations which involve learning Mandarin with more emphasis on Chinese Characters.
 
 Keywords: Mandarin as a foreign language, self-efficacy, exploratory factor analysis, non-native speaker, scale development.
