After a brief poll of folks I know in ministry, here are the best recommendations I have for spiritual gift assessment tools! (Thank you for your input!)
http://www.spiritualgiftstest.com/ Free on-line test or downloadable in pdf format. 100 questions, covers 14 gifts. Results give scores for all gifts, not just top three. Results can be printed or emailed to yourself. Website also has lengthy gift descriptions. Recommended by several pastors. I took it on my tablet!
https://gifts.churchgrowth.org/analysis/index.php Another highly recommended free on-line test with 100 questions.
And finally, here is another downloadable test in pdf format, originally from Lifeway Publishing. Covers 16 gifts, includes definitions and sample of service opportunities. 16 pages. SpiritualGiftsAssessment
The Teacher/Knowledge/Administrator Type.
