Metacognitive monitoring is a significant predictor of academic achievement and is assumed to be related to language competencies. Hence, it may explain academic performance differences between native and non-native speaking students. We compared metacognitive monitoring (in terms of resolution) between native and non-native speaking fourth graders (~ 10 year olds) in two studies. In Study 1, we matched 30 native and 30 non-native speakers and assessed their monitoring in the context of a paired-associates task, including a recognition test and confidence judgements. Study 1 revealed that recognition and monitoring did not differ between native and non-native speaking children. In Study 2, we matched 36 native and 36 non-native speakers and assessed their monitoring with the same paired-associates task. Additionally, we included a text comprehension task with open-ended questions and confidence judgments. We replicated the findings of Study 1, suggesting that recognition and monitoring do not necessarily differ between native and non-native speakers. However, native speaking students answered more open-ended questions correctly than non-native speaking students did. Nevertheless, the two groups did not differ in monitoring their answers to open-ended questions. Our results indicate that native and non-native speaking children may monitor their metacognitive resolution equally, independent of task performance and characteristics. In conclusion, metacognitive monitoring deficits may not be the primary source of the academic performance differences between native and non-native speaking students.
