Is 262 a good map math score for 3rd grader?

There's no standard "Map Math" test with a universally recognized scoring system. To determine if 262 is a good score, we need to know:

* What test is this score from? Different tests have different scoring ranges and scales.

* What is the average score for 3rd graders on this test? A score needs to be compared to a benchmark to assess its quality.

* What is the highest possible score? This will give context to the 262 score.

Without this information, it's impossible to say whether 262 is a good score.
