h. Other more involved investigations in cases where VOSA believe there may be significant abuses, which may include covert surveillance of sites offering MOT tests or at sites where potentially testable vehicles are present. i. Data analysis and/or intelligence may have triggered investigations leading to identification of a deficiency. * Note: Serious corrosion will not normally be considered to warrant disciplinary action, for the application of incorrect testing standards, if it was reported more than three  months after the original test. In the case of other defects, disciplinary action is unlikely to be considered if the fault was reported more than 28 days after the original test.  6 Points Evaluation and Possible Action Points Evaluation 1. Deficiencies found are scored under a points system; the points for particular deficiencies (and for credits) are set out in the appendices listed below.  Shortcomings not listed are allocated the same scores as others of similar seriousness. Subject Appendix Single Offence Cessation 8.1 Incorrect test standards 8.2 Incorrect test methods 8.3 Incorrect operation of MOT Testing Scheme 8.4 Credits 8.5 Action after Initial Assessment of Points 2. The course of action to be taken by VOSA will be determined by VOSA's initial assessment of the number of points scored.  A low score may lead to advice (see paragraph 4 below) being given to the NT and/or AE, whereas a higher score may result in VOSA considering formal disciplinary action.  In the later instance the case will be reviewed by VOSA to determine whether starting the formal disciplinary procedure is justified; if it is not, appropriate advice may be issued to the AE and/or NT. 3. At the end of this section is a flow-chart showing the normal chain of events from the finding of deficiencies to the point at which action is considered. Advice 4. If the points score from a visit or occurrence is below the level shown in the chart at the end of this section, advice will normally be given.  It is not part of the formal disciplinary system and would not be considered directly in any future formal disciplinary action.  However, it can be taken into account in considering the significance of mitigation offered in a formal disciplinary case arising within  5 years of the advice being given.  For any advice to be used in this way it must be given in writing and this will  normally be via a copy of the Vehicle Examiner’s report.    Disciplinary   I The MOT Testing Guide   Issue Date February 2010
