I was most impressed when I was searching for a list indicating the word frequency of Persian words, that I found your list.

I am starting a course to teach both children and adults and will be using your list as a basis for teaching and learning Persian.
(I have successfully used similar lists to teach English.)

One of the things that I have done with your list is use it as the basis for a automated vocabulary assessment.

This program intelligently selects typically 20 words, and based on which of these words the student knows, the program estimates the size of the user’s vocabularly.
(Where there is some hefty maths involved to determine how to most efficiently select which words are asked to the student)

This program can then be run periodically to determine how well the student is learning…

For beginners, a list of 5000 words is more than sufficient for this purpose, however, for more skilled (but not fluent) students the list needs to be significantly larger, to cater for the rarer words.

My technical skills are more in the line of maths, and teaching — with only a modest set of computer programming skills, but it seems that you are far more proficient at databasing than me. Is it possible to re-run your program (if you still have it) to produce, say the top 20,000 words?
