Level C2 has no relation whatsoever with what is sometimes referred to as the performance of an idealized "native speaker", or a "well-educated native speaker" or a "near-native speaker". Level C2 is not intended to imply native-speaker or near native-speaker competence but it characterizes the degree of precision, appropriateness and ease with the language (for more details, see CEFR Companion Volume 2018, p.35).
