Dear Sir or Madam:

To Whom it May Concern:
Our latest records show high levels in productivity for your client, Miss Rebecca Blake. Her grasp of organized study is impeccable, and her time management improves dramatically on a day to day basis. She mastered a particularly stressful week with flying colors, as evidenced by her success in study hours, high productivity in practice sessions, and regular attendance at extra-curricular events. Surely, her hard work and persistence will benefit her greatly in her student examinations next week. We wish her the best of luck.
Regards,
The Boss
