•This paper aims to present the initial findings and item analysis of the IE-ACCME-B test, a multi-method assessment tool specifically developed for evaluating emotional and meta-emotional intelligence in children aged 8 to 11 years. The IE-ACCME-B test was designed within the framework of the meta-emotional intelligence construct and has a dual purpose: 1) measuring emotional intelligence, defined as the ability to perceive, facilitate, understand, and manage emotions, and 2) assessing meta-emotional intelligence, which involves the belief system regarding emotions and awareness of one's own emotional abilities in perceiving, facilitating, understanding, and managing emotions. The analysis of results and items was conducted using CUB models and by examining children's consensus scores.
