Question about Education vs PRO

I am writing on behalf of a Brazilian public school to inquire about subscribing to NextDNS for institutional use.

We are currently evaluating NextDNS on our router and across approximately 60 student devices (notebooks and desktops). We would like to subscribe to the Pro plan; however, the Educational plan is priced beyond what our budget allows. As a public school, we operate with limited self-managed funds and are unable to commit to higher-tier pricing.

It is also worth noting that, under local regulations, students are prohibited from bringing personal mobile devices such as smartphones or tablets to school. All internet access takes place exclusively through school-owned computers and under direct teacher supervision, which significantly limits our overall usage volume and scope.

We would greatly appreciate any guidance on whether the Pro plan would be suitable for our needs, or whether any accommodation could be made given our institutional context.
