All recruitment documentation for TRA facilitated research projects, including the project PLS/PISC, must be developed in conjunction with Research Liaison and Study Coordinator prior to submission for ethics approval.

TRA has a standard approach package for the recruitment of new participants to a project which can be sent through the post or via email. 

An email approach usually contains:

1. The email with a brief summary of the project.
2. A detailed Information Sheet (aka a Plain langue Statement or PLS) outlining the study and the steps involved in participation, written by the researcher in collaboration with TRA.
   • PLS example 1
   • PLS example 2
   • PLS example 3
3. An online TRA Response Form to record the Registry member’s interest in participating, and consent for contact details to be forwarded to the researcher (provided by TRA).

A postal approach usually contains:

1. A signed letter introducing the researcher and research topic (provided by TRA).
2. A detailed Information Sheet (aka a Plain langue Statement or PLS) outlining the study and the steps involved in participation, written by the researcher in collaboration with TRA. 
   
   • Examples as above (must be max 2 pages for a postal approach)
3. A TRA Response Form to record the Registry member’s interest in participating, and consent for contact details to be forwarded to the researcher (provided by TRA). 

When creating these documents it is important to put a compelling case as to why the study is important and why twins can provide greater insights. TRA members get excited about studies that they can see and understand the value of.
