So there's four other elements before you even

put the ed tech in.

Yeah.

I mean, yeah, it's a good question and obviously hardly ever it's just the product.

It's not as if you have a product, you put that in a school and that's going to have that impact.

So many of the studies that we've done when it comes to edtech shows or comes back to this point around implementation, like how is it implemented in the school? and that has all those bits that you listed as part of it and I'm a really big fan of sort of mixed methods approaches making sure that you've got qualitative data as well to really understand how products are implemented in schools and then it's quite interesting when you see a certain impact among certain schools and then not others and having that data then to help tell you that story of like well why is that the case well actually There was no buy-in or support from senior leadership in that school at all or like whatever the reasoning is.

So that implementation piece is always key.

What happens? Do those results get published or do they sort of go under the table from a supplier's point of view? And if negative findings don't see daylight, what does that tell you from a credibility point of view? Because I think we have to talk about the negative stuff as much as the positive stuff.
