The comprehension of connectives, which still develops across primary school age, is an important facet of academic language proficiency. We investigated relations between the comprehension of connectives and school performance in primary school. Drawing on two cohorts with a total of 294 students and two measurement points either in Grades 2 and 3 (Cohort 1; n = 139) or in Grades 3 and 4 (Cohort 2; n = 155), we found positive effects of children's performance on a newly developed test on the comprehension of connectives on reading comprehension and mathematics one year later while considering, amongst others, the families' socioeconomic status, children's nonverbal cognitive abilities, and receptive grammar. Overall, data showed even more pronounced effects of the comprehension of connectives on test scores compared to school grades. Results are discussed with respect to the specific importance of the comprehension of connectives for school performance in primary school.

结语的理解仍在小学阶段发展，是学术语言能力的重要方面。我们调查了对连接词的理解与小学成绩之间的关系。利用两个队列，总共294名学生和两个测量点，分别是2年级和3年级（第1组；n =  139）或3年级和4年级（第2组；n = 155），我们发现儿童表现在一年后进行的一项新的连接词理解力理解和数学测试中的积极影响，同时考虑了家庭的社会经济地位，儿童的非语言认知能力和接受语法等。总体而言，数据显示，与学校成绩相比，理解结语对考试成绩的影响更为明显。讨论结果的过程中，理解连接词对于小学成绩的特定重要性。
