The course covered an introduction to selection, team and game planning, goal setting, tournament regulations and strength and conditioning specifically for sevens.
There were also three practical deliveries where the Ukrainian coaches used the theoretical aspects covered in the classroom.
The trip formed part of the WRU's continued support of the International Rugby Board's Training, Education and Support Programme.
The programme sees all Six Nations countries support tier two, three and four countries with coach educators, trainers and technical support.
"I have never experienced delivering a course and coaching abroad before," said Evans.
"I was able to pass on what I wanted to say through an interpreter and overall it was a fantastic opportunity.
"The coaches were hugely enthusiastic and I was extremely well looked after. I'd like to thank all those who helped in preparing the content of the course which made it such a success."
As well as providing coaching aid to the Ukraine, the WRU also supports Romania, Germany, Luxembourg, Serbia as well as Belgium and Spain in the development of the game.
These projects involve the WRU working closely with the IRB and their Regional Development Manager Europe, Douglas Langley.
The Ukraine trip will be followed up by a similar visit to Kiev in November, WRU Coach Development Manager Tim Hoare delivering a level two coaching course.
Fellow WRU Coach Development Officer Dan Owens delivered a similar course in Luxembourg earlier this year.
"These trips are mutually beneficial to both us and the developing nations," said WRU Coach Development Manager Gerry Roberts.
"We're delighted to support the IRB in their initiatives in other countries both now and into the future.
"Our coaching staff get the opportunity to work in other countries and work on their own coaching methods while hopefully helping others to benefit and develop along the way."
