Assessment of clinical performance could be challenging particularly for novice students. Hence, a new tool Assessment of Clinical Performance in Physiotherapy for novices (ACPP-N) was developed to assess students at the early stage of their clinical placements. Purpose: To validate and measure the reliability and utility of ACPP-N in clinical practice. Method: Thirty-four physiotherapy students in their first and second year, and their clinical educators from a range of practice settings were invited to complete ACPP-N and online survey. Results: Words used in the tool were clear, the domains were proportionately distributed, and the passing score of 60% was a true representation of student’s achievement of learning outcomes. The marking criteria descriptors and the differentiation between “0” and N/A” were clear. All ACCP-N tool items were deemed relevant and appropriate in assessing novice clinical competencies with I-CVI all above 0.79 and S-CVI >0.90. Cronbach’s alpha of 0.89 showed good internal consistency of the N=20 items of the ACPP-N tool. Conclusion: ACPP-N is a valid, reliable, and practical tool in evaluating clinical competencies of novice physiotherapy students.
