The programme included an item on a report by the Commission on School Reform (CRS), described as an “independent group of education experts”, which expressed concern about the performance of Scottish pupils in National 5 exams in science, technology, engineering and mathematics.  A listener complained that the programme failed to make clear that the person interviewed as a representative of the CRS, introduced as a former head teacher and member of the CRS, had strong Liberal Democrat political affiliations.  In the complainant’s view, this breached the section of the BBC’s guidelines on impartiality which says “We should not automatically assume that contributors from other organisations (such as academics, journalists, researchers and representatives of charities and think-tanks) are unbiased.  Appropriate information about their affiliations, funding and particular viewpoints should be made available to the audience, when relevant to the context”.
