The accuracy of skinfold measurements is significantly influenced by the tester's expertise. A knowledgeable and experienced tester understands the correct technique for taking measurements, including how to accurately identify and grip the skinfold, where to place the calipers, and how to read the measurements effectively. They also know the importance of consistency across multiple measurements to ensure reliability.

While the number of sites selected can affect the breadth of body fat estimation, and the sex of the individual may introduce biological differences in fat distribution, they do not directly influence the precision of the measurements as much as the tester's skill level does. Similarly, while the brand of calipers can vary in quality, the measurement's accuracy is more contingent on how well the tester employs the tools provided. Therefore, an expert tester who is proficient in skinfold assessment can significantly enhance the likelihood of obtaining accurate and replicable measurements.
