Introduction and Exam Development Workshops

The description of the entire Linux Essentials Programme programme is listed here.

The purpose of the Linux Essentials Certificate is to define the basic knowledge required to competently use a desktop or mobile device using a Linux Operating System. The associated Linux Essentials Program will guide and encourage youth (and those new to Linux and Open Source) to understand the place of Linux and Open Source in the context of the broader IT industry.

FAQ

Questions and answers on the Linux Essentials Program and Exam are listed here.

Minimally Qualified Candidate Description

This is a description of a candidate that is just barely qualified to pass the LPI Linux Essentials exam. This hypothetical person is called the Minimally Qualified Candidate (MQC). Standards on the Linux Essentials exam should be set so that this person (and anyone more able) would pass but anyone less able would not pass.

The successful candidate should have an understanding of the Linux and Open Source industry and knowledge of the most popular Open Source Applications. The candidate should understand the major components of the Linux operating system, and have the technical proficiency to work on the Linux command line. The MQC has a basic understanding of security and administration related topics such as user/group management, working on the command line and permissions. The Linux Essentials Certificate holder is most likely the end user of a mostly managed system.


The LPI Linux Essentials Certificate Holder MQC typically:

  • Has a basic understanding of FOSS, the various communities and licenses.
  • Understands the basic concepts of processes, programs and the components of an Operating System.
  • Has a basic knowledge of computer hardware.
  • Has a basic appreciation of system security, users/groups and file permissions for public and private directories.
  • Basic understanding of how to make the system accessible and able to connect to other computers on a Local Area Network (LAN).
  • Demonstrates a knowledge of Open Source Applications in the Workplace as they relate to Closed Source equivalents.
  • Understands navigation systems on a Linux Desktop and where to go for help.
