Iteration 1:  6 – 24 June
Iteration 2:  27 June – 15 July
Iteration 3:  18 July – 5 August

NSI Pre-Arrival Physical Training

Military service is a physically demanding profession and requires a high degree of physical preparedness and a healthy constitution. Physical and scholarship qualification processes are independent of each other, but students must receive favorable endorsement in both to receive Navy ROTC scholarship.

Navy and Nurse Option Midshipman Candidates are highly encouraged to prepare for NSI by visiting the Navy Operational Fitness and Fueling System (NOFFS) website and by downloading the NOFFS Endurance App on their mobile device. NOFFS was developed by Navy fitness stakeholders, in partnership with industry leaders in human performance, to provide a complete physical training program that will ‘eliminate the guesswork’ for the individual Sailor who is participating in his/her personal, physical training program.
Marine Option Midshipman Candidates are highly encouraged to prepare for NSI by downloading the USMC Squad Bay App for their mobile device. The Squad Bay app challenges aspiring Marines to track fitness progress and learn about the Marine Corps and the demanding and transformative process of Officer Candidates.

NSI 2024 Graduation

If you have guests that plan on attending the NSI Graduation Ceremony in person, YOU MUST fill out the NSI Graduation Ceremony Guest Form and submit it when you arrive for training. Due to the length of time required to conduct background checks on anyone wishing to attend the ceremony, once you submit the form, changes will not be allowed. If you aren’t sure if someone will be able to attend the ceremony or not, it is highly recommended to put the person on the list because you won’t be able to add them after you submit the form should their schedule happen to “free up”. There will be more information posted on this website and social media in May when the NSI 1 assignment roster is released.
