You could let the link go to for example mypage.html?ref=myschool where mypage.html is the location of your webpage. You could add javascript to your page to check if ref=myschool is in the link. (it is called a get variable) if it is, you can set a code in the box.
On this page: http://scripts.franciscocharrua.com/javascript-get-variables.php is explained how to read a get variable with javascript, you should check for the variable ref.

However, if this code really only needs to be available for everyone in your school this is not very safe, you should use a server side scripting language like php instead.

Basically there is nothing you can do ACROSS two different domains; if that service page doesn't belong to you, browsers will probably deny to do the job.

BUT.

If that form is something simple, you can reimplement it (view source, save, and a little editing) so that you'll have a copy of it that posts exactly the same informations for their server.  Now this is YOUR form, sending informations to THEIR server which is okay by default (unless they have some protection), and with your form, of course, you can do whatever you wish, fill in fields, or even change the whole logic.  All that matters is that you send the same POST-data as the original form.

If you have questions about this, give me some details.

Okay, getting it now, I hope XD

I think you want this:

REPLACE:
<input name="DistrictCode" type="text" id="DistrictCode" class="textEntry" />

Open in new window

WITH:
<input name="DistrictCode" type="text" id="DistrictCode" class="textEntry" value="CC-SDA" />

OR... and while I was checking, I accidentally noticed that that page already has the following functionality:

https://www.renweb.com/Logins/ParentsWeb-Login.aspx?district=CC-SDA
Works I guess..

because if you make a typo, it shows it filled in:
https://www.renweb.com/Logins/ParentsWeb-Login.aspx?district=CC-SDAWRONG
