Inquiry
I would like to know why there are names and list numbers (for the same exam, Exam: 7005, COMPUTER SPECIALIST (SOFTWARE), with a total list size of 2,403 names) that show up on Civil Service List (Active) Dataset, but do not show up on the Civil Service List Certification dataset? found here:
https://data.cityofnewyork.us/City-Government/Civil-Service-List-Certification/a9md-ynri/data
From own review, the only difference I can find between the two datasets are the names listed on the "Civil Service List Certification" dataset have been contacted by multiple NYC Agencies to attend a hiring pool (going by the "Request Date" and "List Agency Desc" fields).
There are people who are present on both the Active & Certification datasets who have been given "Request dates" on the "Civil Service List Certification" dataset who have a high list numbers (example list numbers: 2352, 2360, 2364, 2369, 2370, 2379, 2382, 2385, 2394, 2396, 2403). While there are list numbers present on the Civil Service List (Active) dataset with lower list numbers who are not listed at all on the "Civil Service List Certification" dataset (example: 476.5, 527.5, 606.5, 1073.5, 1163.5, 1358.5, 2226, 2237, etc...). Why is that?
In another case I've actually found a person with 1 list number displayed on the Civil Service List (Active) dataset (example: 1428.500,), but the same exact person has two list numbers (same exam: 7005) on the "Civil Service List Certification" dataset (example: 603.500 and 1428.500,) who appears to have been contacted multiple times recently for both list numbers to attend a hiring pool. Would someone from the NYC Open Data team be able to investigate the possible discrepancies and help clarify the differences between the two data sets?
Assigned Agencys Response
You inquired concerning Exam No. 7005, Computer Specialist (Software), and the data for that exam on the Civil Service List and Civil Service List Certification datasets.
As you observed, the number of entries on the Certification dataset is substantially greater than the number of entries on the Civil Service List dataset, as a new record (row) is created each time an eligible candidate is included on a list certification to an agency. A single eligible candidate may be called on numerous certifications/hiring pools during the lifetime of the list.
With respect to candidates on the eligible list whose names do not appear on any certifications, those candidates may have taken other jobs, withdrawn themselves for consideration, or may have been disqualified. With respect to Mr. Delaude, his correct list number is 1428.5.
