What is the most common assessment tool for sexual maturity?

Tanner's 5 stages of assessment is recognized as the most common tool for evaluating sexual maturity because it provides a standardized framework for assessing the development of secondary sexual characteristics. The Tanner stages, also known as the Tanner scale, delineate the physical changes that occur during puberty in both boys and girls, including breast development, pubic hair growth, and genital maturation. This method allows clinicians and researchers to categorize individuals based on observable traits, making it easier to assess their stage of development and associated health considerations.

In contrast, other options focus on different aspects of health or development. A health screening questionnaire typically assesses overall health risks, rather than specifically focusing on sexual maturity. The Body Mass Index (BMI) chart is used to evaluate weight relative to height and does not provide insight into sexual development. Similarly, a puberty development checklist may offer a more general view of developmental milestones but lacks the specificity and widely accepted classification system found in Tanner's stages. Thus, Tanner's 5 stages stand out as the preferred and most common assessment tool for determining sexual maturity.
