A letter that someone writes about you to showcase how you are as a student, employee, and/or person. Some colleges/universities, some scholarships, and some employers require a letter or two for applications and prefer a teacher who knows you fairly well. Our BHS Common Scholarship application requires two letters of recommendation.
Letters can be from teachers, coaches, employers, club advisors, school counselors, principals, etc. Competitive colleges usually prefer a core (English, Math, Science, Social Studies) teacher to write a letter.
