Because the demographic composition of neighborhoods and schools overlaps, their effects on educational attainment are not independent of each other. Throughout the early teenage years, the timing and duration of exposure to neighborhood and school contexts can vary, advocating for a longitudinal approach when studying schooling outcomes. This study uses Avon Longitudinal Study of Parents and Children data (N = 4502; 49% female) to examine how exposure to poverty between ages 10–16 predicts educational attainment. The results indicate that enduring exposure to neighborhood poverty relates to educational attainment, while timing does not. For school poverty, longer exposure is related to lower attainment, but earlier exposure has a stronger impact than later exposure. Adolescents who were exposed to poverty in both contexts for the full observation period had the lowest educational attainment. The findings highlight the importance of understanding when and how long adolescents are exposed to contextual poverty.

由于社区和学校的人口构成重叠，它们对教育程度的影响并不是相互独立的。在整个青少年早期，接触社区和学校环境的时间和持续时间可能会有所不同，因此在研究学校教育成果时提倡采用纵向方法。本研究使用雅芳父母和儿童纵向研究数据（N = 4502；49% 女性）来检验 10-16 岁之间的贫困如何预测教育程度。结果表明，持久暴露于邻里贫困与教育程度有关，而时间与教育程度无关。对于学校贫困，较长时间的接触与较低的学习成绩相关，但较早的接触比后来的接触具有更大的影响。在整个观察期内在这两种情况下都处于贫困之中的青少年受教育程度最低。研究结果强调了了解青少年何时以及多长时间处于环境贫困中的重要性。
