If OP is 11th grade he/she can't open the application for his year group yet without entering inaccurate information. Recommend he not open an application for the current year group. That just adds one more scholarship that needs to be processed.
Here is what the instructions are in the applications for this year. Nothing says they won't change for next years application:
School of Intent
- When requested below, select the name of the college or university offering ROTC you wish to attend. Please specify a minimum of one school choice, but a maximum of seven.
- If you are applying for a scholarship in the Nursing or Engineering fields, ALL selected school choices must be Accredited Nursing or Engineering Program schools.
- If you are applying to a Historically Black College or University and you have indicated above that you desire to compete for a scholarship to attend a Historically Black College or University and are awarded an ROTC Scholarship, then you MUST attend a HBCU. When choosing schools below you must have the very 1st priority pick as an HBCU.
- Only schools with active ROTC Scholarship programs will appear in the list below.
- To add a school choice, select the school choice drop down box, State and School Name and the press the UPDATE LIST button.
- When selecting school choices, the application process requires that at least one of your choices is a college in your home state of residence.
- To Delete a school choice, click the red X next to the school choice that you wish to remove.
- After pressing the UPDATE LIST button, your selection will appear in the list below.
- School choices are listed in priority based on the preferences of where you wish to attend.
- To change the priority order of the selections that you have made, remove the items, then select them in the order you wish them to be in.
- When selecting school choices, the application process requires that 3 of your 7 choices are public colleges or universities. If you select fewer than 6 schools, then 2 of the 5 choices must be public colleges or universities. 3 or fewer choices, 1 must be a public college or university.
- Continue with this process for the school choices and prioritize as you desire. After reviewing your list, press the Save button.
You don't need to enter 7, and I wouldn't limit myself to 7 on your initial list of schools. Use 7 as a rough guide, but I recommend you look at as many schools as you can/want to to find the right fit.
With regard to applying to multiple academies/ROTC programs...Although there is nothing saying you can't do it, in my mind if I know that an applicant is applying to all the programs and they can't explain to me why they don't care whether they will serve as in the Army, Navy, Air Force, Marines, Coast Guard then I'm assuming they are more interested in getting free school than they are in carefully considering what it means to serve as an officer in a particular branch.
