This textbook addresses the main assessment issues that teachers and educational institutions face in their daily work, while providing practical tools to support actions and decisions in this area. The critical issues observed in the assessment practices are made visible and specific guidelines and examples are given on how to carry out an effective and realistic classroom assessment within the school context. The book reveals evaluation elements that future and practicing teachers need to know about and can benefit from, such as the alignment between curriculum, teaching and assessment, flexibility in the construction of instruments according to their purpose, effective feedback, rubrics to evaluate performance and the use of specification tables to make pedagogical decisions (beyond the construction of the instruments itself).
