It does get quite tricky when there's cultural and comorbid kind of question mark, cognitive factors at play as well. And that's when you do need to be really careful about what your, I guess, observing, and you're making the distinction between letting them have enough time, I guess to settle in and observe them in terms of their English as a second language or the different cultural background factors versus it's just a cognitive difficulty. And I think it does require a period of time to make that observation and to, I guess, impute a disability, if there is the ESL factors at play, because that is a really tricky one. And we do get that from time to time. I'm sure all teaching staff have experienced that. And it is quite frustrating because you're not sure what factors are really contributing to the educational outcomes of that child, but that is about putting in as much support and intervention I think as you can, and then giving it a reasonable period of time. And I think if they're just new to the country or school or environment, then you do need to have sort of two, three years of observing them and working out if this is cognitive or if this is really demonstrated by ESL factors.
