A lesson level serves as a training level for the rest of the game, and shows most of the tiles the player can encounter. The term can refer to:
- The first eight levels of Chip's Challenge 1, entitled Lesson 1 through Lesson 8
- The first nine levels of CCLP1, though not labelled in numeric order
- Seven levels in Chip's Challenge 2, entitled Lesson 1 through Lesson 7, though not the first seven levels
All of these levels contain a hint which explains the main concepts introduced in the level. The CC1 and CC2 lesson levels were all designed by Chuck Sommerville, whereas the CCLP1 lesson levels were primarily designed by Tyler Sontag and Henry Potts, with just one being designed by J.B. Lewis. They can also refer to 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 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.

Other level sets
Unlike Chip's Challenge 1, CCLP2 and CCLP4 do not have lesson levels, as they use the same devices and mechanics as the original, and are meant to be played by veteran Chipsters. However, CCLP3 has the introductory Entrance Examination, where most of the basic mechanics are put into test for newcomers.
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. For example, pi's lesson 3.141592653589793238 introduces the set's use of the digits of pi as a method of solving its levels.
