Please note that only those journals listed in the Journal Citation Reports of Clarivate Analytics will have Journal Impact Factors (JIF). Many journals in India do not come under the impact factor scheme of Clarivate Analyitcs. The National Academy of Agricultural Sciences (NAAS) has recognised this fact and came up with a scheme for agriculture and related disciplines. According to the scheme, each journal is assessed, and its relative merit and standing among researchers is indicated by giving points out of a maximum of 20.

Before assigning points, NAAS first ascertain whether the journal is already having an ‘Impact Factor’ of Clarivate Analytics. For those journals where JIF is available, the scores are assigned as 6.00 + Impact Factor up to 20.00 (category I), and for those journals where JIF is not available, the rating is from 1 to 6.00 only (category II). The academy periodically revises its rating. The rating is available from http://www.naasindia.org/rating.html.

In short, those journals having NAAS rating upot 6.00 will not have any impact factors!

NAAS rating of journals is given by the Indian national institute where as the Impact factor is given international body based on the number of citations of the Journal articles. Hence it is very important to consider the impact factor journals rather than NAAS rating.
