HI dude! I researched the web and this is what I found.
I am also giving you a link but I will paste parts of the text that deal with need for supervisors review. Hope you will get some information out of this.
This is a guideline for IOs (their Field Manual) when they finished initial examination (interview)
-You must grant an application if the applicant meets all statutory requirements for naturalization (see 8 CFR 335). In order to understand each of the specific statutory requirements, familiarize yourself with the sections of this manual relating to: residence, Chapter 73.1 - 73.5; good moral character, Chapter 73.6; English and Civics, Chapter 73.8 and Attachment to the Constitution, Chapter 73.7.)
You must make a decision whether to grant an application either at the time of the initial examination or within 120 days after the initial examination. [See section 335 of the Act and 8 CFR 335.3.)
If a case does not require NQP supervisory concurrence, you may tell the applicant at the end of the interview that his or her application has been approved and that he or she must take the oath of allegiance to complete the citizenship process. Also provide the applicant with an N–652, a form used to record the applicant’s interview results. See also Chapter 72.2(d) for a more complete discussion of forms used during the process. Once you decide to grant the application, you should take the following processing steps that are detailed in the following questions and corresponding answers below..bla bla bla...
Here is next:
8) Naturalization Quality Procedures (NQP). NQP requires that you take several steps when approving an N–400. For details regarding the specific NQP requirements, see Appendix 72-1, NQP Sections V, VI, and VII.
In certain situations, NQP requires that a supervisor review a naturalization case before it can be officially granted. To review these specific situations and the nature of the review, see Appendix 72-1, NQP Section VI.
To ensure that all steps in the processing of the N–400 have been followed and annotated on the processing worksheet, and as a final check to ensure that USCIS does not naturalize an ineligible applicant, the NQP includes a reverification procedure for all approved applications. To review the reverification procedures, see Appendix 72-1, NQP Section VII.
Make sure that you understand and comply with the NQP. First, you should have received the required NQP training and you should stay abreast of any NQP changes. Second, carefully and completely fill out the N–400 adjudications processing worksheet while you are conducting the interview. Complying with the NQP procedures and properly filling out the worksheet will ensure that anyone who reviews your work will see a file that accurately and clearly reflects the quality work you have done.
A re-verifier is not responsible for re-adjudicating cases. However, as a USCIS officer, if he or she notices that an applicant has not established eligibility, the officer has the responsibility to take the appropriate action. Moreover, re-verification does not replace normal supervisory responsibilities and duties.
