A grade level (based on the USA education system) is equivalent to the number of years of education a person has had. A score of around 10-12 is roughly the reading level on completion of high school. Text to be read by the general public should aim for a grade level of around 8.

Answer

"Flesch-Kincaid Reading Ease	83.2"

This is quite a high score! It ranges from 0 to 100. This usually means that around 55 is considered  an okay-score. Anything under 55 would be a failed mark.

"Gunning-Fog Score	6.7
Coleman-Liau Index	7.8
SMOG Index	5.1
Automated Readability Index	2.2
Average Grade Level	5.2"

All these scores are related to the readability of the text.
Like it mentioned, a score of 10-12 is roughly the reading level on completion of high school.
However, a general text that should be readable by most people would be around level 8.

You can consider level 6 to 8 quite decent, when it comes to readability.

Your average score is 5.9. (I left out the Automated Readability Index, since it so much lower than your averages scores, I believe the calculation does not work on your particular test.)

Since this is based on calculations and averages, I personally wouldn't consider this a good system to check your readability. Let someone else read your text, here on iTalki or anywhere really. ^^

Good luck with learning!
