Problems students encounter with understanding the abstract concept of chemical bonding, as revealed in previous research, are outlined. The development of a two-tier multiple-choice diagnostic instrument for assessing alternative conceptions about chemical bonding held by 14–16 year-olds is described. The instrument was administered to 119 chemistry students and the results analysed. The common alternative conceptions they were found to hold are listed and discussed. It was found that this instrument provided an easy-to-administer tool, providing results in a readily accessible form.
