TEDS 21 Login

We have now launched! 

We have now sent invitations to all TEDS twins and all TEDS parents, some by email and some by post. If your invitation has not arrived, of if you have mislaid your login details, please contact us!

How do I use the app?

iPhone users: search for TEDS 21 on iTunes (note the space between TEDS and 21!)

Android users: search for TEDS21 (no space between TEDS and 21) on the Play Store.

When you have downloaded the app, enter the username and password that we sent you, and you will be able to start!

How do I take part on the web?

Twins follow this link: https://studies.teds.ac.uk/join/teds21.

Parents follow this link: https://studies.teds.ac.uk/join/teds21p.

Your username and password are the same as for the app.

Can I complete the questionnaire on paper?

Yes! Contact us and we will send you a copy.

How do I deal with technical problems?

Don't hesitate to contact us if you need help.

If you have problems downloading or installing the app, please try using the web (links above) or ask us for a paper questionnaire.

If you have got half-way through the questionnaire in the app, and you don't want to start all over again, you can log in on the web using this alternative link, which will allow you to pick up where you left off: https://app.studies.teds.ac.uk//#/login.
