The player can check their map, hide in the blue lockers and use Dirty Chalk Erasers to avoid being seen by any of Principal of the Things. If a Principal sees the player for more than half a second, that Principal will begin chasing after them immediately while they scold them for being in the Super Schoolhouse after-hours.
Unlike in other modes, once the Principals scold the player, they will never lose track of the player and will always try to find the shortest path to them. After that, while hiding in the blue locker, they will keep moving around near the locker. If the player gets out of the locker, they will immediately get sent to detention.
As stated before, Baldi is not a threat unless the player is sent to detention because he will always be waiting for them in the Principal's office. Also, all characters cannot escape from this location because there is no door to other locations and there are no items that the player can use to get out of the room.
This technically makes the Principal of the Things the ones that can cause a game over in this challenge.
On the map, Principal of the Things are marked as gray arrows ().
Stealthy Challenge's was likely made by using a in-between version of the Level Generator with Endless Mode, with its seed being 99. This can be assumed because of some properties, like how there are 7 notebooks, and only 1 exit. However, the map does lack a big room (i.e the Cafeteria/Playground).
Baldi's Basics Plus[]
Since V0.4, the player can no longer hear Baldi's ruler slapping unless they have been caught by one of the Principal of the Things. This is due to the sound propagation system as the Principal's office in this challenge does not have any door, so no sounds can be heard from outside.
Prior to V0.3.3, the acronym was C1. The previous acronym is now used on the Speedy Challenge. Plus, there was a door to the Principal's office, but it cannot be opened. This door was replaced by a window in V0.3.3.
In this version, a chalkboard in a classroom and a poster in another were removed for unknown reasons.
In V0.8 Pre-release 2, along with other challenges, Stealthy Challenge was unavailable due to preparing new level system for pre-made levels.

Glitches[]
General[]
The window with the wall lacking texture.
The clear mask as seen in Baldi's Basics Plus.
A window with the gray colored wall texture.
In Baldi's Basics - Challenges Demo, one of the windows of a faculty room had an untextured (white) mask.
Prior to Baldi's Basics PlusV0.1.5, the untextured mask was clear.
From V0.1.5 to V0.3.2 of Baldi's Basics Plus, the clear mask had a gray color.
This glitch was fixed in V0.3.3 of Baldi's Basics Plus by implementing the level editor.
Baldi's Basics Plus[]
Rarely, Principal of the Things' arrows do not appear in the map.
In V0.1.5, all Principal arrows on the map were pointing up regardless of the direction of these characters moving.
In V0.3.3, Principals could scold the player for running in the Principal's office.
From V0.3.3 to V0.3.7, the entrance of one of the faculty rooms was blocked by a wall, so it could not be accessed. However, the door could still be interacted with through the wall. It was possible to hack the game to use a Portal Poster to get inside or by noclipping inside.
From V0.3.5 to V0.3.7, a faculty door to this room had added in the hallway. However, the player still could not enter the room because the wall blocked the entrance after opening a door.
