Which is not a type of evaluation?

Educational evaluation involves systematically gathering and analyzing information to determine the effectiveness of teaching and learning processes. There are several recognized types of evaluation, each serving a distinct purpose and occurring at different stages. The question asks which option is NOT a type of evaluation.

• Formative evaluation is conducted during the learning process to provide ongoing feedback and improve instruction and learning.
• Summative evaluation is conducted at the end of a learning period to assess overall achievement and assign grades.
• Diagnostic evaluation is conducted before or during instruction to identify students' strengths, weaknesses, and prior knowledge to tailor teaching.

Decorative is not a recognized type of educational evaluation. The term 'decorative' refers to something ornamental or aesthetic, which has no direct function in assessing learning or instructional effectiveness. The other options are standard and well-established categories in educational assessment. Therefore, 'Decorative' is the correct answer.
