Narrative:

After receiving our IFR clearance and calling taking off runway 36 at auo over CTAF; we proceeded to take off runway 36. Before we had cleared the departure end of the runway; a jet called taking off right turn out. Climbing through 1600; our tis traffic alert came active. I initially thought this to be a ghost signature that sometimes appears while first receiving tis information. However this was a [light transport aircraft]. He was showing less than 1/8 mile same altitude behind us. He passed us off our right side at our same altitude at a distance of 300-500 feet and proceeded to turn left across our nose as we were entering IMC. My student; the pilot flying froze and proceeded to let go of the controls. I announced that I had the flight controls and took evasive action in order to avoid potential impact from the citation maintained altitude while performing a steep 45 degree bank to the left while maintaining altitude. The jet climbed into IMC conditions and proceeded to then pick up his clearance. We were just crossing into a layer when we were forced to take evasive action.this whole incident could have been avoided if: the [aircraft] had picked up his clearance on the ground. The jet exercised proper spacing considerations on takeoff especially with a much slower aircraft in front.things I believe I could have done better: I should have realized quicker that the alert was not a false alert and took sooner evasive action by descending. I could have taken the flight controls from my student earlier when I realized that it could have been a situation in which evasive maneuvers would take place. Overall; this was a terrible experience especially on my student's first flight into IMC.
