Leading up to 2010, the Australian Research Council’s Excellence in Research for Australia (ERA) initiative categorized journals (and conferences) into four categories A*, A, B, and C (see this Wikipedia page for details).
C-ranked journals (with the lowest ranking) are described as journals:
that do not meet the criteria of higher tiers
which is not particularly informative.
I’m not sure if this initiative excluded journals that would be considered predatory (check your email spam folder for examples of predatory journals). B or higher ranked journals would not be predatory, as there are people who vouch for them as containing some high-quality publications. I’m not sure how the C journals were included.
Question: Does inclusion on the ARC ERA 2010 journal list imply the journal is not a predatory journal?
