System Scan

The System Scan (身体検査 (システムスキャン)) is a regular city-wide testing event in Academy City to determine the power levels of the espers with it, and is part of the Power Curriculum Program. Each esper is given a different type of test depending on their esper power. The test then determines how powerful their ability and/or how much control they have over it.

It is shown that one is tested in 6 attributes to determine one's level, each attribute has a grade for each one, and can strangely be an individual esper power in itself. Although it is unknown if this applies to every esper. There are only 5 attributes that are known as of now, these are: Precognition, Clairvoyance, Psychometry, Telepathy, and Psychokinesis. These attributes including the power level of the esper are later saved into the city's Data Banks.

However, the System Scan is not perfect, as one gains a Level 0 if the esper's power cannot be detected or measured, as is the case of Kamijou Touma. This applies to Sogiita Gunha as well whose powers cannot be truly understood and as such was categorized as a Level 5.

Level Upper Incidents
The most recent System Scan was held in July 16, the day that Uiharu Kazari and Saten Ruiko met Misaka Mikoto. At Tokiwadai Middle School some of the ability testing included tests such as a tester holding up a card and having the esper use their power to figure out what shape is on the back of the card. Another test is seen to be having a telekinetic bend a piece of metal to a certain degree to determine their accuracy.

It is seen that Shirai Kuroko's test involved seeing how far and accurate she could teleport a ball-sized object. Her result was that it was teleported to a distance of 78.23 meters away and was 54 centimeters away from the target. This confirmed her classification as a Level 4 esper. Misaka Mikoto's test involved her firing her railgun into a pool several times. This was done with the pool as it was needed to dampen the destructive force of her power. Even with the pool each railgun caused the water to shoot up higher then the nearby school building. It was also loud and powerful enough to be heard and shake up the entire nearby school area knocking Kongou Mitsuko onto the ground. Her test results found that her railgun had a initial velocity of 1,030 meters per second and she had a continuous discharge rate of 8 per min. Her accuracy was so good that in the test she had a target deviation of only 18.9 millimeters. This re-concluded that she was a level 5.

Later that day after classes at Sakugawa Middle School ended, Saten Ruiko and Uiharu Kazari talk about their System Scan where each maintained their previous levels: Kazari at Level 1 and Ruiko as Level 0.

In a later episode, Level Upper users were scanned after they attended the class for them, here Ruiko and her friends discover that their attributes have increased, although their level remained.
