While other assessment methods of aptitude testing, such as interviews, assessment centers, or CV analyses, provide information about the behavioral repertoire that test takers currently possess or have demonstrated in the past, psychological tests focus on more permanent and fundamental characteristics of individuals. The statements that can be made through psychological tests can not only be used to explain current behavior, but also shed light on statements about the potential of individuals that may not yet have been realized. Potential assessments can thus not only be used to distinguish between currently suitable and unsuitable individuals, but also to identify those individuals who show increased development potential in line with the requirement profile. Depending on the results of the requirements analysis, several assessment procedures may be useful in answering the question. In this case, an approach that integrates all available sources of information is recommended.
Psychological tests also offer incremental advantages for clinical and neuropsychological assessments compared to other methods such as interviews, exploratory conversations, or purely observation-based procedures. While interviews and anamnestic procedures primarily provide retrospective or subjective information, tests capture the patient's fundamental, measurable characteristics and abilities in a standardized and objective manner. Psychological tests enable a differentiated and quantifiable assessment of cognitive, emotional, and behavioral characteristics that can be compared with age- and population-specific reference groups through standardization. This objectivity and reliability minimize the distortions that can arise from subjective assessments or situational influences (Fimm et al., 2023; Thöne-Otto et al., 2020; Müller et al., 2019). For example, the guidelines of the German Society of Neurology explicitly emphasize that attention performance cannot be assessed on the basis of clinical impression alone and that standardized testing procedures are therefore indispensable (Fimm et al., 2023).
While interviews and observations provide important contextual information, tests create a reliable basis for valid, comprehensible, and reproducible statements about the assessment condition, as emphasized in the guidelines for neuropsychological assessment of the Society for Neuropsychology (GNP) (Neumann-Zielke et al., 2015).
The following criteria for psychological tests are of utmost importance in practice: objectivity, reliability, criterion validity, fairness, and economy. The advantages of the SFS Test Solutions with regard to these criteria are explained in the chapter: Evaluation.
