Unfortunately, what you describe is an issue that I have come across quite a bit over the last 27 years of consulting with federal contractors. The perfect scenario would be that all persons who applied were given a disposition that was clear enough to determine if they are an internet applicant. Only those that pass the internet applicant rule are counted in the applicant/hire analysis. However, in this situation where not everyone was assigned a disposition code and there is a lack of records to determine the correct disposition, there might be some things that can be done to accurately disposition some of those records such as determining if anyone applied after the requisition was filled. In this case, the disposition could be "req filled". Is there a way to determine if any candidates were not reviewed at all? If so, these individuals could be dispositioned as "not reviewed" or "not considered". Any candidates left without a disposition code could be reviewed to determine if they met the basic requirements. If not, they could be dispositioned with a "did not meet basic req." Otherwise, any candidates where you cannot accurately determine their disposition should be left blank and the assumption would be that they are an internet applicant and would, therefore, be counted in the applicant/hire analysis. Feel free to reach out if further clarification is needed (email@example.com).
