What do I need to know when I interpret my speed test results?

Speed tests measure the unused bandwidth available throughout your building—not in the room where they're run. If a school runs a speed test in 5 rooms and finds each time that 200 students can test, the school can test 200 students at the same time. 

You should still check every room, though, because wireless speed typically varies throughout a building. If you check the speed in each testing room, you can identify the rooms with the best and worst connectivity.

If the speed test results in 4 of the 5 rooms show that 200 students can test, but the results in the 5th room show that only 170 students can test, the school should:

• Run the speed test again to make sure the low number wasn’t an anomaly.
• Avoid using that room. 

You should also remember that Bluebook is designed to minimize bandwidth needs. In any testing session, demands on the network are staggered because students are timed individually. Their test doesn't start until they enter a code provided by the proctor in their room. Even students in the same room will enter the code at slightly different times.
