Whereas other databases describe exposure frequency to written words (Manulex, Novlex), \u00c9OLE documents spelling production by describing, for each grade, the actual state of lexical acquisition. The success rates were established from words dictated in context at the end of the school year to 48,902 pupils from 464 schools across France. Each word was written by at least 40 pupils at each of the five grade levels, resulting in the analysis of 2,368,885 spellings. The database also specifies the grammatical category of each entry and identifies the 136 words affected by the 1990 French spelling reform, tested both in France and Canada. A word is conventionally considered to have been acquired at a given grade when 75% of the tested pupils spell it correctly. This threshold is intended as a descriptive, not a prescriptive, benchmark; users should consult the interpretation guidelines before using the database. In particular, a pupil should not be judged for failing to spell correctly a word considered &#8220;75% acquired&#8221; at their grade level, as this would fundamentally misrepresent the purpose of the database. By construction, up to one quarter of pupils at that grade do not spell such words correctly, without this being pathological or even cause for concern.<\/p>\n\n\n\n\n<h3 class=\"wp-block-heading\">Interpretation Guidelines<\/h3>\n\n\n\n\n<p><a href=\"http:\/\/www.lexique.org\/wp-content\/uploads\/2026\/07\/EOLE_-presentation_lexique-org_11-juillet.pdf\">Detailed presentation document for \u00c9OLE.<\/a><\/p>\n\n\n\n\n<h3 class=\"wp-block-heading\">Download<\/h3>\n\n\n\n\n<p><a href=\"http:\/\/lexique.org\/databases\/Eole\/EOLE.xlsx\">\u00c9OLE Excel file<\/a><\/p>\n\n\n\n\n<h3 class=\"wp-block-heading\">License<\/h3>\n\n\n\n\n<p>\u00c9OLE data (including query results) are made available with the explicit written permission of the copyright holders, in accordance with the terms of the Creative Commons Attribution\u2013NonCommercial\u2013ShareAlike 4.0 International License (CC BY-NC-SA 4.0).
