I found it a bit strange also. Like you, I thought the only thing needed to be a cleaner was a high school diploma, which I have and wrote down on the application they gave me when I went to Livingston street. Though they never asked to see my actual high school diploma, which I brought with me when I went down there both times. Perhaps I should have shown it to them, even though it was clearly stated on my application that I graduated high school, but no one at the desk asked for it. I thought there would have been a more formal sit down after I did my medical exam, but I did not even get the chance to come in for a medical. I am very surprised that they said I was not chosen to be appointed to the cleaner position based on their review of my qualifications, which could only be from the application that I filled out when I went there. Very strange and frustrating, unless they changed the qualifications that a cleaner needs to have, but I doubt it. It's a shame because I took this test for conductor in 2008, and I really was hoping for the opportunity to get in to the MTA as a cleaner, I really needed it, but no luck. As you said I need to keep trying.
