To whom it may concern,

I find myself extremely delighted to present a recommendation for one of my best research assistants, Daphne Simsek, for admission to the graduate program in Plant Pathology at your esteemed school. I have known Daphne for more than three years in my capacity as Agricultural Engineer at Directorate of Plant Protection Central Research Institute.

I came to know her very well when she was an intern in my department during summer of 2010. During her internship, Daphne demonstrated the ability to work independently with great creativity and enthusiasm she had the terrific ability to draw on her own experience and observations to develop thoughtful opinions on a variety of day to day issues in our lab. I can surely say Daphne was one of our finest, most well-rounded interns at that summer

In late 2011, I was looking a field research assistant to work with us on "Determination of Rhizoctonia Species, Classic-Molecular Characterization of Anastomosis Groups and the Reactions of Some Wheat Cultuvars with Potential Biocontrol agents on Wheat Production Areas of Central Anatolia Region" project which was a collective project with Ankara University and The Scientific and Technological Research Council of Turkey. Surprisingly, I came to know that Daphne was a Master student in department of agriculture at Ankara University, without thinking I offered field research assistant position to her and she accepted. We worked over 8 month on this project, and we did ... < We are going to add more things here just simply ignore>

Daphne is not only a smart and orderly student but also her talent is the most striking. She is very hardworking, neat, energetic, motivated, and careful. Daphne is full of initiative and ready to take on any given responsibility. She is capable of doing advanced research and indeed very keen to finish a given job in the earliest possible time

I'm sure you will find her to be a student whose talents will only shine further through your graduate program. It is my hope that you will accept her admission to your university. Feel free to contact me if you require further information.

Thank you April April, I made those change, Do you have any other suggestion to make this letter looks better? Can you give me a sample sentences for this ' I think you should add some more details describing what characteristics and qualities of Daphne that made you choose her for the position immediately.'

Thank you
regards,

--> My suggestion: "As I contacted Daphne's professor, I came to know that she was among the most assiduous and devoted students, and that she not only took full responsibilities for her work but also endeavoured to learn from other people and strived to ascertain the best solution to each and every problem. Those qualities made her stand out among other candidates for the position and without hesitation,...". I made up some characteristics about her. What you write in this letter depends on your real first impression about her.

Oh and by the way, I think you should address her as "Ms. Simsek" instead of "Daphne", it will give the letter a sense of formality.

Just my opinion. Hope it helps.
Best
