Check my grammar, please,....?

Here's an edit to consider and make your own: Hope it helps.

The Head of Academic Services certifies that John H. (a student from the Professional Career of Education Faculty of Education of this Institute); reached the Upper Tenth of his Class during the academic periods of 2010-1 and 2014-2.

The above-mentioned student obtained such acknowledgment with a weighted average grade of 16.35. The student also occupied 7th place in the indicated period on the Honor Roll for Academic Performance.

The Head of Academic Services certifies that the grades of student John H. from the (Professional Career of Education, Faculty of Education - THIS IS CONFUSING) of this Institute, were in the top 10% of his class for the academic periods 2010-1 and 2014-2. (Are you sure you mean 2014-2?)

The above-mentioned student had a weighted average of 16.35. The student occupied the 7th Place in the Honor Roll for Academic Performance in the indicated period. (Since there are two periods given in the first paragraph, you should say "indicated periods.")

If you're really referring to only one period, then what does "2010-1 and 2014-2" mean?

BASED ON YOUR 'COMMENT', HERE IS A REVISION TO MY ANSWER:

For the period 2010 - 2014, John H., a student in the Professional Career of Education, Faculty of Education, achieved grades that were in the top 10% of his class. Mr. H's grades had a weighted average of 16.35, and he was 7th place in the Honor Roll for Academic Performance in the indicated period.
