Drawing on knowledge about the development of reading comprehension, and empirical insights into the effects of training on students' learning strategies and reading-related metacognition, we developed a parent–child reading program for implementation in the home environment. The results of this first quasi-experimental evaluation study indicate that it is generally possible to implement a program of this kind within the family setting, but that participation is low and selective based on family background and children's achievement level. Nevertheless, participation in the program was found to have substantial effects on the development of vocabulary and on reading-related metacognition, indicating that family-based reading programs have considerable potential. The issues of selective participation and the lack of a program effect on text comprehension are discussed, and prospects for future research on systematic reading training in the family context are considered.
