Level 3 is the top category of the Publication Forum classification. Level 3 is a sub-category of the level 2, so level 3 channels need also to meet the level 2 criteria. Level 3 can include the topmost publication series of various disciplines meeting also the following criteria:
• The research published in them represents the highest level in the discipline and has very high impact (e.g., as measured through citation indicators);
• The series cover the discipline comprehensively, not limiting to the discussion of narrow special themes;
• Both the authors and readers are international and the editorial boards are constituted by the leading researcher in the field;
• Publication in these journals and series is highly appreciated among the international research community of the field.
The Panels will prepare a proposal of publication series to be rated as level 3, and the Panel Chairs take consensus decisions to include publication series in the level 3 category.
