Assessment plays a significant role in language education as it provides information about learners’ proficiency and assists in formulating teaching strategies. The research work examines a reading comprehension test administered to a 16-year-old grade 10 student at school, who is studying English as a foreign language. The study analyzes validity and reliability of the chosen assessment tool. A qualitative case-study approach was applied to analyze a B2-level reading comprehension test adapted from CEFR examination materials. The participant completed the reading comprehension test, and the assessment items were evaluated against fundamental principles of language testing proposed by Brown (2010), Bachman and Palmer (1996), and Hughes (2003). The findings demonstrated that while the assessment test showed high scoring reliability and practicality through its objective multiple-choice format, several items lacked construct validity as these items measured vocabulary knowledge rather than reading comprehension.
