How to assist Junior Engineers to become future leaders

I was asked by a Junior Engineer to provide him with a written recommendation for his next career move, having excellent interpersonal communication but lacking in depth of experience, it was a little challenging in the fact that he just graduated with very minimum technical experience, after describing his duties at our firm, I wrote the following:

In regards to referring persons for employment, simply speaking, we refer them as to traits of experience and traits of character. In my 30 plus years with the Engineering Division in technical and managerial capacities I firmly believe that competence in the 1 Matter more than makes up for any lack in the former.

  In XXXXXXX case we need to accentuate the latter. Being long on education, he is necessarily short, time-wise, on experience. XXXXXX was pleasant to work with - there was no resistance. He was interested in doing whatever task to my satisfaction. While recognizing his own limitations, he was eager to solve problems on his own, XXXXXX is worthy of trust. We did not hesitate to trust him as to reliable results in the quantity checks. XXXXX himself stated that because we put trust in him it made him want to try all the harder to do a good job for us. XXXXXX is a good combination of eagerness, reserve and initiative. I would recommend him highly as productive, teachable and personable.

 Our young engineers are our future, and they need our support in order for them to excel in their career.
