Dr. Rosalyn Tamming:

For example, in the review of the CDNTs, we had - I do not have the exact figures - approximately 4,000 responses from parents to our survey about their views on CDNTs. We then held a number of follow-on focus groups. We have gathered a huge amount of information from that.

We regularly engage with DPOs, which represent the views of their members, many of whom are parents who have particular issues.
