What do the most-used acronyms on this forum mean?

[Heliotrope]

In some topics acronyms are being used a lot, and while some are obvious (IS, IT, etc.), some are not. It almost seems like sometimes some people want to impress others by using as many of them as possible, or don't realise not everyone knows all these acronyms. I'm sometimes lost, and Googling them doesn't always help.
Can anyone produce a list of the most-used ones?

I've got a short list here:

ITT = ?
EPP = ?
DS
DE
 = ?
QTS = Qualified Teacher Status
NQT = Newly Qualified Teacher?
BS = ?
SEC = ?
EP = ?
ET = ?
OP = Original Poster
SES = ?
MPS = ?
IOC = ?
SEN = ?
LCSA = Latin or Central & South-America?
EAP = ?

Any additions/solves?

There is a lexicon entry here:

To add to your inquiries:

ITT = Initial Teacher Training; the general term used in the UK to describe the program used for the education of professional teachers.
EPP = Educator Preparation Program; a general term for educating programs of professional teachers in the US.
DS
DE
 = Not one acronym but a composite of 2 DS and DE. DS = Domestic School, DE = Domestic Education, usually ascribed as DS/DE.
QTS = Qualified Teacher Status (Yes).
NQT = Newly Qualified Teacher (Yes)
BS = British School
SEC = Socio-Economic Class
EP = English Program; an academic program that regardless of goals, outcome, content and curriculum is delivered in English. Usually used to describe a program when the focus is unclear or bridges between ESOL education and academic education. Typically when your looking at such a classroom it looks like a typical academic classroom but the pacing is slower, the scope and sequence is broader and more tasking is spent on vocabulary and language acquisition of the academic content.
ET = English Teacher
OP = Original Poster (Yes). Not to be confused with LW = Letter Writer.
SES = Socio-Economic Service; a term used to describe the differences when a significant disparity exists between students/parents. A classic example is an affluent DS/IS that has X number of students from a lower Socio-Economic Class who are attending on scholarship. In IE it usually refers to the differences between tuition paying parents children and teachers children who are attending the IS as part of the ITs comp.
MPS = Main Pay Scale; this is the standard salary scale used in UK DSs that entry level DTs start on. As teachers progress up it they can apply at the threshold to be placed on the UPS (Upper Pay Scale), this is a discretionary salary scale, that the DT most meet individualized criteria establish by the DS to cross over.
IOC = International Olympic Committee; this is the organizational body that regulates the Olympic Games. Within IE its relevance is in regards to the individual member sports regulating bodies. An IT whose primary tasking in an IS (typically a PHE/PE/PSPE IT) is going to want to focus on competition and coaching qualifications that are regulated by whatever body is recognized by the IOC.
SEN = Special Education Needs; the term generally used in the UK to refer to services and programs that address the needs of students with various disabilities. This is the equivalent term in the US to "SPED, (Special Education) and LD (Learning Diversity) in the IB, and to a broader extent LS (Learning Support).
LCSA = Latin, Central & South-America (Yes)
EAP = English for Academic Purposes; a program of study that focuses on language acquisition (CALP = Cognitive Academic Language Proficiency) to a high level within a specific academic or technical context. In the EE (English Education) field you generally see this in technical fields like medicine, law, business or engineering. In IE its usually the designation for ESOL specific courses/classes within a bilingual or immersion program DS/IS.
