I work for the federal government. I recently applied for a new position. The public job announcement was advertised on usajobs.com. There was an error in the announcement (later confirmed by Human Resources), but it was never amended before the job announcement closed. It has never been amended. I have now been selected for the position.

My question is: is the agency responsible to honor what was announced in the vacancy? I know in other federal government vacancies, when there is an error, I have seen the vacancy is amended and it is clearly stated why.

In my case the agency is stating that the promotion potential is GS-9, the announcement stated promotion potential is GS-11.

Here is what the application stated:

If you are selected, you will be required to:
-- Work in collaboration with your supervisor and the Upward Mobility Coordinator to develop and sign a formal training plan within 30 days of being placed in the Upward Mobility position.
-- Complete self evaluations and receive supervisory evaluations every 90 days while on the Upward Mobility training plan.
-- Complete the training plan successfully in order to be promoted to the target grade level. (Note: time-in-grade restrictions are waived and specialized experience requirements are shortened for promotion from the GS-07 to the GS-09 level.)
-- Meet standard career-ladder promotion policies and procedures to be promoted to the GS-11 level. Promotion beyond the target level is based upon the following criteria: 1) you meet the basic qualification requirements (time-in-grade and specialized experience) for the next higher grade level; 2) you have demonstrated the ability to perform at the next higher grade level; and 3) your performance appraisal at time of review was at least fully successful.
