He does not look like he's in 7th grade at all. He's like 5'10" and looks like a Sophomore or Junior. He is almost 16 and is incredibly mature as a runner. He is very experienced with club running and will likely to be slow to progress his way down to sub 4 (but probably will do it by his senior year if he can stay healthy).
Jake Ogden of Dana Hills on the other hand looks like he is a true Freshmen and has a lot more room to grow.
If the "average" freshman turns 14 on July 2nd (midpoint of year) a few months before they start high school, that means this kid is about 7 months older than the average based on the previous poster citing a NOV birthday.
With that in mind, consider the following data, based on the top 50 performers nationally in 2013 outdoors, according to Milesplit.
1st - 4:04.45 by The Boss - Senior
Tied for 11th - 4:11.10 by Austin Tamagno - Freshman
50th - 4:15.00 by Jacob Thomson - Senior
Senior in Top 50 - 37
Juniors in Top 50 - 12
Sophomores in Top 50 - 0
Freshmen in Top 50 - 1
