he distinctions between testing intelligence and testing for knowledge are critical, especially in educational and professional assessment settings.

@Glyka Angel Raganas rightly points out that intelligence tests are best suited for identifying cognitive potential or learning difficulties, whereas knowledge tests are more appropriate for measuring mastery in specific subjects. I agree that using either in isolation may give an incomplete picture—especially when we aim to support learner development holistically.

@Yasin Sancak adds an important layer by discussing the cultural and socioeconomic limitations of intelligence testing. This is particularly relevant in diverse educational settings, where students’ prior exposure to learning opportunities varies widely. His point about aligning the assessment type with the purpose resonates with best practices in fair and valid testing.

@Christian Charles Lester Doblados effectively categorizes the differences and tools used in each type of test. I found his comparison between IQ tests and curriculum-based exams especially helpful in visualizing how each method serves a different evaluative purpose.

In my view, the key takeaway is that both intelligence and knowledge tests have their place—but their effectiveness depends on context. For example, a student struggling with math might benefit more from a diagnostic intelligence assessment to uncover processing issues, while an end-of-term exam would more accurately reflect their subject knowledge.

A blended approach, combining both types of testing when appropriate, often gives educators a fuller understanding of a learner’s abilities, limitations, and potential.
