I completed one term of a master's program before finding it was not what I expected, so I promptly quit. Now, I am sending fall application letters to other master's programs, for which I will be a paying student, but am uncertain how to mention this previous program, or whether that is even necessary. I do intent to send a transcript, as I want to transfer a few credits, however, should I mention this elsewhere in my application? Place a line on my CV? Mention this previous program in my application letters? Offer an explanation upfront describing why I left the program?
I found generally useful advice in Is transferring to another university an option for an unhappy PhD student?, but the answers do not explain what etiquette one should follow in reporting such a situation.
