Developing assessment instruments after writing the performance objectives in the design process makes teaching more effective. It allows for better individualized learning once the assessment instruments are developed and instructional designers can focus on developing instructional strategy to address the learners' needs and achieve the desired performance levels. The difference between the Dick and Carey Model and ADDIE Model is the ongoing revision and how it could take place in the design and development process. 

Strengths of the Dick and Carey Model in Teacher Training

Prioritizing feedback and evaluation throughout the process creates engaging and relevant instructional materials designed to their needs. Giving teachers opportunities through conductive and summative evaluation helps to assess the effectiveness of the instructional materials. The model can also be used to assess teachers' prior knowledge and learning needs from former trainings then redesign instructional strategies and materials to cater to the objectives. 

Limitations of the Dick and Carey Model in Teacher Training 

Feedback from teachers may not be taken in consideration or prioritized for the conductive and summative evaluation process. Depending on the complexity, it may be deemed time-consuming, especially for novice instructional designers.
