Performance based assessment is an activity or reading that allows a student to demonstrate their proficiency with skills or knowledge learned in a particular unit. I have developed many performance assessments and also worked on scoring PBA for the state.
Benefits - greater picture of student achievement, more overarching
Drawbacks - need teach in a particular way to allow students to practice skills. Time consumptive grading
Students working together to complete a task. Students doing lab/group work. Students are able to interact with each other to complete a goal. Bigger groups may get off task easier.

Drawbacks: Students lose focus and are distracted in large classroom settings
