{{Quote|All cooperative testing courses begin at this central hub. From here we transport you to the new testing course. |GLaDOS|Portal 2|Filecoop hub track14-16.ogg}}

The '''Computer Intelligence Training and Enrichment Center''', '''Human Test Subject Research Center''' or '''CInTEC''', referred to by GLaDOS as the  '''Hub''' for brevity,''Portal 2'' is a large, towering room that is the selection point for each of the Cooperative Testing Courses throughout the Aperture Science Aperture Science Enrichment Center|Enrichment Center in ''Portal 2''.

Consisting of Aperture Science Panel|toggleable platforms, Aperture Science Aerial Faith Plate|Aerial Faith Plates, and Aperture Science Hard Light Bridge|Hard Light Bridges, these elements allow a unique path for ATLAS and P-body to traverse around the Hub.

== Overview ==
*Throughout the cooperative campaign, ATLAS and P-body use the Hub in order to select different Test Courses to explore. The courses, in order, are called "Cooperative Testing Courses#|Team Building", "Cooperative Testing Courses#|Mass and Velocity", "Cooperative Testing Courses#|Hard Light Surfaces", "Cooperative Testing Courses#|Excursion Funnels", "Cooperative Testing Courses#|Mobility Gels" and "Cooperative Testing Courses#|Art Therapy".
*After completing a course, the next is opened, allowing access to more chambers. In cases where one player has opened more courses than the other, it defaults to the more-experienced player.
*A large screen features both separate and combined information of the players, including how many steps each has taken, number of portals placed, disasters averted, collaboration points, numbers of times they hugged, and so on.
*The Hub may have been designed and entirely constructed by GLaDOS alone as the cooperative testing initiative was her creation.

==Behind the scenes==
The Hub was originally non-linear, with all courses open from the beginning. The intent was to let players move on to other courses should the ones they are attempting frustrate them. However, this confused players, so the developers opted for a linear path of courses.''Portal 2'' commentary 

*If a player presses the "use" button on the small "409" box next to the level select panel, it will emit a purple light and sounds of the Aperture Science Sentry Turret|turrets in cheerful free fall lines.{{YouTube|NCFxbJYyf9g|''Portal 2'' - The Hub Easter Egg}}
*If viewed through the Player View window, the statistics screen appears completely black.
*In the hallways where the player can choose what level to play, the monitors display the FileLab monitor screen text.png|cake recipe seen on computers in the original ''Portal''.
