...praise the excellence of your program and the quality of your graduates.
I am motivated to write this letter to praise the excellence of your program and the quality of your graduates. I have had the opportunity to employ two of your graduates. Both were excellent employees. They came with a solid knowledge base and practical skills that could immediately be employed, this thanks entirely to your program! Also, thank you very much for all of your efforts in finding me suitable employees. You have worked very hard to provide me with wonderful candidates. Potential students should know that your program would provide them with marketable skills. Potential employers should also be aware of this and that you are extremely helpful in matching candidates to positions. Thank you again.
