Internal Evaluation covers an in- depth investigation of the value of the material in relation to its objectives, principles, lesson design, and assessment procedures. At this stage, the evaluator analyzes the extent to which claims in the introduction and blurbs actually match up with the internal consistency and organization of the materials. In order to perform effective internal evaluation of the material, at least two units of a book or a set of materials need to be inspected. The following information may be analyzed:
- Presentation of the skills in the material
- Grading and sequencing of skills
- Authentic or artificial recordings
- Authentic or artificial dialogues for speaking
- Relationships of tests and exercises to learner needs and course content
- Provisions for different learning styles and self-study.
- Motivation for the learners
