We have no reason to criticise the work of ISC Research mentioned in the article “Teachers flee UK for sunnier future” (March 19), and there was no suggestion in the piece that we were involved in its work. But just in case any readers were confused we would like to point out that ISC Research is not affiliated to the ISC and its research is entirely unrelated to our own.
