Validity is a core topic in educational and psychological assessment. Although there are many available resources describing the concept of validity, sources of validity evidence, and suggestions about how to obtain validity evidence; there is little guidance providing specific instructions for planning and carrying out validation studies. Method: In this paper we describe (a) the fundamental principles underlying test validity, (b) the process of validation, and (c) practical guidance for practitioners to plan and carry out sufficient validity research to support the use of a test for its intended purposes. Results: We first define validity, describe sources of validity evidence, and provide examples where each of these sources are addressed. Then, we describe a validation agenda describing steps and tasks for planning and developing validation studies. Conclusions: Finally, we discuss the importance of addressing validation studies from a comprehensive approach.

The main objective of the research was (1) to identify different profiles of students based on three purposes they had for homework (academic, self-regulatory and approval-seeking) and (2) to analyze their relationship with the homework effort, completion, and math achievement. Method: The study involved 3,018 eighth-grade students from various areas in China. Data were analyzed with Mplus using Latent Profile Analysis (LPA).

During the 20th century the alpha coefficient (α) was widely used in the estimation of the internal consistency reliability of test scores. After misuses were identified in the early 21st century alternatives became widespread, especially the omega coefficient (ω). Nowadays, α is re-emerging as an acceptable option for reliability estimation. Method: A review of the recent academic contributions, journal publication habits and recommendations from normative texts was carried out to identify good practices in estimation of internal consistency reliability. Results: To guide the analysis, we propose a three-phase decision diagram, which includes item description, fit of the measurement model for the test, and choice of the reliability coefficient for test score(s). We also provide recommendations on the use of R, Jamovi, JASP, Mplus, SPSS and Stata software to perform the analysis. Conclusions: Both α and ω are suitable for items with approximately normal distributions and approximately unidimensional and congeneric measures without extreme factor loadings. When items show non-normal distributions, strong specific components, or correlated errors, variants of ω are more appropriate. Some require specific data gathering designs. On a practical level we recommend a critical approach when using the software.
