‘Emerging adulthood’ is the name given to the phase between childhood and adulthood. Our twins have now reached this point and are starting to make their own way in the world: moving away, working, going to university and generally becoming more independent. As this transition is so varied (while some chose to stay at home, others move to the other side of the world) we will be interested to look back at the predictors of outcomes in emerging adulthood as well as looking forward to their goals, ambitions and plans for the future.

We need your help!

This is where our TEDS twins come in! Like all our research, we could not do it without the continued support from our twins and their families who spend time filling in questionnaires, completing online tests and even help us with testing and piloting. TEDS 21 will be our next stage of testing and we hope to get information from all of our twins! This might seem like an enormous challenge (we have over 10,000 active families), however the TEDS team is up for the challenge and are thinking of clever and innovative way to make testing a little more exciting than just pencil and paper.

TEDS’ new way of testing

….Introducing the TEDS app! We are currently designing a new app for our TEDS families to use. This will provide them with an easy way to fill in questionnaires and details wherever they are. But fear not, if apps aren’t your thing, TEDS families will also be able to access the testing site below. But that’s not all – we are also designing a TEDS game (a few sneak peek pics below!)


We are almost ready to launch. We will be inviting you to take part in TEDS 21 soon! Watch out for invitations.

When will we be launching TEDS 21?

We are currently in the piloting phase for the questionnaires, making sure that they are all working properly before we implement them into our new app. The app itself is in development and we hope to have it ready for January 2017. We will then be contacting all of our twins and inviting them to take part from Spring 2017 onwards.
