(Posting on testing children’s English the appropriate way; by one NEB)
Testing children’s English cannot take the form of a written test of multiple-choice items. There have been a lot of arguments about this. Testing children’s English is best aimed at their primarily speaking and listening skills—separately or combined. Techniques for doing this can be devised to the best interest of the children and the attainment of the learning objectives. This video shows one such a technique https://www.youtube.com/watch?v=TTO9-4rhaKY.
“Making tests relevant: Children relate to the world quite differently from adults. The first language skills to develop are normally in speaking and listening, and that is where the emphasis in testing children should be. Topic areas should be chosen which are relevant to children’s lives – such as school, food, sports and animals – and all language should be used in an everyday context, matching the way in which young learners process language” https://www.teachingenglish.org.uk/article/young-learner-testing.
