Basically learning and teaching Aikido are two sides of the same hand.
In our lineage we say when you start your own dojo you get shodan. As this is the first step to independence and finding your (W)way. This does not mean you then go without a teacher
In the past my teacher suddenly start asking if I had started my own dojo yet, which off course I had not. Next time I saw him, again the question. Then you start :-)
