The IC tool developed during the fellowship is the first of its kind in terms of design, content, and purpose. No other tool uses the inductive learning method adopted, instead of predefined, deductive methods. The Tool presents a solution to an imperative and critical matter in intercultural assessment and the designing and implementation of intercultural education, which is at the very heart of the European Union’s educational policies. Unlike other intercultural assessment tools, the app will (1) allow learners to dynamically and systematically highlight and self-reflect on the different sets of intercultural competences elicited as a reaction to each intercultural experience, and not be confined with one format of interculturality, (2) take context into account during assessment and also planning of intercultural activities, (3) be a personalized account of IC progress adaptable to age-diverse audiences instead of answers to hypothetical questions that are out of students’ experiences, (4) be a developmental/diagnostic tool rather than a placement or summative one, which will minimize unethical judgments of students intercultural competences. The Tool, especially when developed into a social media-like App, could greatly help learners, teachers and educational institutions better develop and assess intercultural competences, thus contributing to the creation of future generations that are more open and accepting to diversity, who can effectively and efficiently deal with differences, misunderstandings, or conflicts.
