Delta is a horizontally scrolling shooter computer game originally released for the Commodore 64 by Thalamus Ltd in 1987. It was programmed by Stavros Fasoulas and the music was written by Rob Hubbard. The menu-music is based on the theme of Koyaanisqatsi by Philip Glass and the in-game-music is based on Pink Floyd's On the Run. The game was also released for the ZX Spectrum in 1990 as Delta Charge.

The game was released as Delta Patrol in the United States by Electronic Arts for its Amazing Software line of action-oriented software programs, in 1987 on the Commodore 64.

The player controls a spaceship and gains power-up points by destroying formations of enemies. Some enemy formations instead subtract power-up points for the player, so the player must take note of which formations to destroy. Periodically blocks containing the power-ups (higher speed, faster rate of fire) appear and the player can pick one of them up: The more points the player has collected, the more powerful are the power-ups that can be chosen. Unavailable power-ups are gray and kill the player if he flies into them, making them part of the obstacles in the game. The effects of the power-ups are lost over time and must therefore be regained. The player gets a choice between in-game music or in-game sound effects. There is also a high score table but no way to save it when the game is turned off.

The game title music was covered by Desert Planet in their 2003 album Joystick Pop.

Delta (Diploma in Teaching English to Speakers of Other Languages) is an English language teaching (ELT) qualification for experienced Teachers of English as a Foreign Language (TEFL) and Teachers of English to Speakers of Other Languages (TESOL). It is provided by Cambridge English Language Assessment through authorised Cambridge English Teaching Qualification centres and can be taken either full-time or part-time.

Delta is designed for candidates with previous English language teaching experience. Candidates have usually completed an initial teaching qualification and typically have at least one year’s teaching experience. It is suitable for first language and non-first language speakers of English who are teaching English as a second or foreign language (ESL and EFL) in primary, secondary and adult contexts. Candidates should have English language skills equivalent to at least level C1 of the Common European Framework of Reference for Languages.

Delta consists of three modules, which can be taken together or separately, in any order, and over any time period. Module Two requires course attendance at an authorised Delta centre so that teaching practice can be supported and assessed. There is no requirement to take a course at a recognised Delta centre for Modules One and Three, although most candidates do. Successful candidates receive a certificate for each module passed, as well as an overall certificate upon the successful completion of all three modules.

All three modules emphasise both theory and practice, although teaching practice is only directly assessed in Module Two. Delta also gives teachers an opportunity to pursue areas of specialism in Module Three (an extended assignment on syllabus design, course planning and assessment in the context of a selected ELT specialist area, or an extended assignment on ELT management in the context of a selected management specialist area).

Delta is designed to help candidates to develop as teachers and progress to new career opportunities. It is regulated at Level 7 of the Qualifications and Credit Framework for England, Wales and N. Ireland and is suitable for teachers at Developing or Proficient level on the Cambridge English Teaching Framework.
