I use our ESGI assessment to track phonemic awareness activities. One assessment I give is onset and rime. I give the test one on one and just say words broken into onset and rime such as /c/. /at/ and the student has to tell me cat. If they have mastered that I go on to breaking words into phonemes such as /d/ /o/ /g/ and the student has to tell me dog. If they can do that then I give them a CVC word and have them read it. With the ESGI I simply mark yes and no and it generates a report for each child and for the entire class.
