Frequently asked questions
Is the payment one-time or recurring?
One-time payment per project. No monthly subscription or hidden charges. You contract a complete diagnosis including the entire process from start to finish.
What if I want to repeat the diagnosis next year?
You can contract a new diagnosis whenever you need it. Many schools do it annually to measure climate evolution. Returning schools receive a 15% discount.
How long does the survey take to complete?
The survey takes 8 to 12 minutes per student. It can be completed from any device, during school hours or from home. Typically completed in 3–5 business days.
How secure is my students' data?
The data is the exclusive property of the institution. It is never used for advertising or shared with third parties. Responses are completely anonymous β€” no one can be individually identified.
Can I fund it with the school budget?
Yes. The TECH4ZERO diagnosis can be funded through school climate funds, administrative or counseling budgets. In Chile it can also be funded with SEP resources.
Do you work with school districts or only individual institutions?
We work with both. For districts or school networks we have special proposals with consolidated pricing. Contact us for a personalized proposal.
