Diagnostic and prognostic tests are crucial in teacher education programs for assessing and enhancing the abilities of future educators. Diagnostic tests identify current knowledge, skills, and gaps, allowing for personalized learning plans and timely interventions. These include initial assessments of entry-level competencies and ongoing formative evaluations to monitor progress and provide constructive feedback. Prognostic tests predict future teaching success by evaluating aptitudes and professional dispositions, guiding career development and aligning strengths with suitable roles. An integrated approach using both test types ensures a comprehensive understanding of candidates, facilitating data-driven decisions in curriculum design and support services. However, ethical considerations like fairness, bias, and privacy must be addressed, along with practical challenges such as resource allocation and continuous test improvement. Overall, these tests enhance the effectiveness of teacher training by preparing competent and effective educators. Sarita Anand
