Here is the link to follow to read about the new standard:
In a nutshell... starting January 1 of 2018, ALL Recruits will be required to pass an initial run standard BEFORE they commence basic military training. If they do not pass the initial run standard they will be given one more chance within a 48 hour period to retest and pass. If they fail to meet the requirements for the initial run standard they will be separated from the Navy with an entry level separation, which allows them to reapply at a later date with a waiver from Navy Recruiting Command.
