Human Factors
My student and I performed the Practice VOR-A approach into AJO. While in contact with SoCal Approach; we made contact with the CTAF reporting a 6 mile final and 4 mile final call. After the frequency change we heard of traffic in the downwind turning base. The spacing looked appropriate when that traffic turned final and we made another call stating that we were on final behind that traffic. The traffic ahead performed a touch-and-go and we thought we were number 1 for the runway. When we were short final for runway 25; we noticed a Cessna less than 100 ft. off our nose to our 11 o'clock and slightly lower. A go-around was immediately performed to the North and a modified base to final was made to a full stop landing. [At] Our final destination a report to ATC was made.I had instructed the student to remove his instrument training device well before the incident occurred.Our position was reported several times.It is possible that; given the busy training environment; a radio call was missed; however; the student and I do not recall ever hearing the other aircraft call its position.The slightly lower aircraft was a high wing aircraft. The aircraft we were flying was a low wing aircraft.An effort to visually confirm that final was clear was made by the student and myself.
Flight Instructor reported an NMAC while on short final.
