What is one method used to improve screening accuracy?

Employing multiple assessment approaches is a recognized method to enhance the accuracy of screening. This technique combines various tools and methods, which can include direct observations, standardized tests, and parent or teacher questionnaires. By integrating different perspectives and methodologies, the likelihood of obtaining a comprehensive understanding of a child's developmental status increases. This multifaceted approach helps to minimize biases that might arise from a single assessment tool or observer, leading to more reliable and valid results.

Other methods, such as solely relying on one individual's observations or delegating responsibility exclusively to parents, would limit the scope of information and may introduce subjective biases. Furthermore, merely increasing the age of children evaluated does not directly contribute to improved screening accuracy as it does not address the variety of factors influencing development and assessment outcomes.
