Common App Teacher Recommendation is a recommendation form that teachers fill out for students who are applying to college using the Common Application. This form allows teachers to provide their insights on the student's academic performance, personal qualities, and overall potential. It usually includes information about the teacher's relationship with the student, the courses taught, and their assessment of the student's abilities and skills. This recommendation plays an important role in the college application process as it provides colleges with an additional perspective on the student's abilities and achievements.
