Thank you for your correction.

Following the link allwording.com/certificate-appreciation/,
you can find templates of Certificate of Appreciation designed for different occasions\groups of people.

My biggest doubt is whether the formula can be applied to the short-term training in question. Maybe a letter of gratitude would be more relevant.
Still if you insist, I would think of:

                   Certificate of Appreciation
 Faculty of Science and Technology appreciates
