School attendance and school completion are important benchmarks of successful development. Unfortunately, school absenteeism and school dropout remain debilitating and prevalent conditions among youth. Stakeholders invested in promoting school attendance and reducing school absenteeism generally agree that multifaceted ecological frameworks are needed to account for these heterogeneous problems as well as differences across local education agencies and broader jurisdictions. A multi-tiered system of supports (MTSS) framework emphasizes many aspects that match well with school attendance and its problems, including prevention and a continuum of supports, screening, evidence-based assessment and intervention, problem-solving and data-based decision-making, implementation fidelity, and natural embedding into extant school improvement plans. This article outlines a multidimensional MTSS model for school attendance and absenteeism to account for recent developments regarding service delivery within schools. Such developments include integrated models of multi-tiered service delivery to concurrently address multiple domains of functioning, the development of more nuanced approaches for students with various challenges, and consideration of three-dimensional (pyramidal) perspectives to allow simultaneous and yet nuanced strategies for several domain clusters. Sample domain clusters common to the literature that could populate the multiple dimensions or sides of a MTSS pyramid model for school attendance and absenteeism are presented. These domain clusters include (1) school refusal/truancy/school withdrawal/school exclusion, (2) functional profiles and analysis, (3) preschool/elementary/middle/high school, (4) ecological levels of impact on school attendance and its problems, and (5) low/moderate/high absenteeism severity. Recommendations are made as well regarding broader MTSS integration and implementation science vis-à-vis school attendance and its problems.

上学和完成学业是成功发展的重要基准。不幸的是，旷工和辍学仍然使年轻人处于衰弱和普遍的状况。投资于提高学校出勤率和减少学校旷工的利益相关者普遍同意，需要多方面的生态框架来解决这些异质性问题以及地方教育机构和更广泛的司法管辖区之间的差异。多层支持系统（MTSS）框架强调了许多与学校出勤率及其问题相匹配的方面，包括预防和连续支持，筛选，基于证据的评估和干预，解决问题和基于数据的决策。制定，实施保真度，以及自然地融入现有的学校改善计划中。本文概述了针对学校出勤和缺勤的多维MTSS模型，以说明有关学校内部服务提供的最新发展。这些发展包括多层服务交付的集成模型，以同时解决多个职能领域的问题，为面临各种挑战的学生开发更细微的方法，并考虑了三维（金字塔）视角，以允许同时采用但又细微的策略域集群。提出了文献共有的样本域簇，这些样本域簇可以填充MTSS金字塔模型的多个维度或侧面，用于学校出勤和旷工。这些领域集群包括（1）学校拒绝/逃学/学校退学/学校排斥，（2）功能简介和分析，（3）学前/小学/初中/高中，（4）生态水平对入学率及其问题的影响，以及（5）低/中/高缺勤率。还针对针对学校出勤率及其问题的更广泛的MTSS集成和实施科学提出了建议。
