A lesson level can refer to the first eight levels of Chip's Challenge 1, entitled Lesson 1 through Lesson 8, and seven levels in Chip's Challenge 2, entitled Lesson 1 through Lesson 7, though they are not the first seven levels. They serve as training levels for the rest of the game, and show most of the tiles. All of these levels contain a hint which explains the main concepts introduced in the level. They were all designed by Chuck Sommerville. They can also refer to the nine tutorial levels in CCLP1 or other similar levels in custom level sets
CC1 lesson levels
- Lesson 1: The basics: Chip, floor, walls, hints, computer chips, sockets and the exit, plus keys and locks.
- Lesson 2: Blocks and how they turn water into dirt; monsters, specifically the bug.
- Lesson 3: The elements and their respective boots.
- Lesson 4: Blue buttons and tanks, green buttons and toggle walls, and items or destructive obstacles hidden under blocks.
- Lesson 5: Red buttons and clone machines, brown buttons and traps, and bombs; gliders, fireballs, and pink balls. Lesson 5 is also the first level not to contain a socket or any computer chips.
- Lesson 6: Invisible walls, hidden walls, blue walls, and the concept of superfluous (unreachable) chips.
- Lesson 7: Thieves, teleports, and recessed walls. It also features thin walls in a cameo role.
- Lesson 8: Gravel, dirt as a default tile, and the teeth.
Tiles not introduced in the CC1 lesson levels
- Walkers were first introduced in Nice Day.
- Clone blocks were first introduced in Iceberg.
- Blobs were first introduced in Blobnet.
- Paramecia were first introduced in Chchchips.

Unlike Chip's Challenge 1, Chip's Challenge Level Pack 2 does not have lesson levels, since it uses the same devices and mechanics as the original, and it's meant to be played by veteran Chipsters. However, Chip's Challenge Level Pack 3 has the introductory Entrance Examination, where most of the basic mechanics are put into test for newcomers. Chip's Challenge Level Pack 1 contains nine tutorial levels, none with their title in the Lesson # format.

Other than the official CC1 and CC2 lesson levels, the term is used to identify any level made in this style, usually introducing a concept not covered in the official lesson levels or to introduce a gimmick of a specific custom level set, such as pi.dat's lesson 3.141592653589793238 that introduces the set's use of the digits of pi as a method of solving its levels.
