According to the January proceedings report from the NCAA's Division One Men's and Women's Track & Field and Cross Country Committee, a "recommendation" has been brought forth proposing that the number of regional qualifiers in individual events for the East and West Regional Championships be reduced from 48 qualifiers to 32 qualifiers only for the 2021 outdoor track season.
The reduction in field sizes aims to address ongoing concerns regarding the spread of COVID-19, "while also being more fiscally responsible both to the NCAA and participating institutions" according to the report.
For perspective, here were the athletes who were ranked at #32 in their respective regions for each distance event during the 2019 outdoor track season...
NOTE: The below marks do not consider scratches. Conversions are taken into consideration and denoted next to the time if applicable. These marks are not necessarily automatic qualifying times, but simply reference points as to how fast the 32nd ranked individuals in each distance event were in their respective regions. The recommendation applies to all events, not just distance events.
