Supplements & Codes

How do I save my application/recommendation to come back later?

You can click the tab at the top of your screen to trigger the save function. Additionally, any time you click Submit the form saves. You can still come back and keep editing it until the form deadline. Clicking submit multiple time only saves the new version of the form. This will not duplicate your form. 

Why does my supplement code not work?

If you received an instruction email to fill out a supplement for an applicant, and the code does not work, it is very likely that the applicant has deleted the request sent to you. Please check with the applicant to ensure that this is the case.

Also, please make sure that the error is not because of a typo, so, instead of typing it, please copy and paste it into the "Supplement Code" field.

Do I need a supplement code or a program key?

Applicants or students wanting to apply for a scholarship would need a program key, while recommenders, nominators and the like would need a supplement code. Our clients provide program keys for their programs on their website. Applicants generate supplement codes from their applications when applying. If you do not have a Program Key, please send an email to with the name of the scholarship to which you want to apply. Our team will get you the key you need! 

How long do I have to complete a supplement?

When you receive a supplement request email, a deadline date will be provided in red. A deadline will also be available on your home page. 

How do recommendations and supplements work?

In order to offer a secure application environment, most recommendations or other supplement forms required from a third-party must be filled out via that third party's own account in the ISTS system. An applicant will request a supplement to be filled out by a nominator or recommender. Then, the recommender would have received a system-generated email asking them for their assistance which would include instructions and a supplement code. 

How do I use a supplement code?

Please do the following steps to complete the supplement form:  

  1. Go to
  2. Log into or create your AIM account with ISTS
  3. Once logged in, click "Fill out a supplement" from the right of the home page.
  4. Enter your supplement code from the email
  5. Fill out and submit the resulting form.

What is my supplement status?

The status of your recommendation is always available to you from your home page of your ISTS account. If you ever need to get back to the home page, click Home in the upper right of your screen. Under "Supplements" on your home page, a table will appear with all active supplement forms. If a student does not appear, you have not used their supplement code on this account. Note that if you have more than 10 supplements on your account, you will need to change pages to display further supplement items.   You can organize supplements on your home page by Applicant Name, Program, Due Date, or Status. A status of Not Submitted means that all required information on the form has not been successfully submitted. Click the form name under Program to continue filling out the supplement. A status of Submitted means that all materials have been received and no further action is required for that supplement form.
