exam, not the 2012 exam.

See attached documentation provided by Westinghouse.

XXI. Random Selection Methodology For the random selection of both the RO and SRO exam, the random number generator is seeded with the ticks from the system clock. This helps to ensure a different seed every time an exam outline is generated.

Random Selection: RO Exam Create two identical lists of systems for Tier, ROGroup, Category Generate Random Number Between 1 and number of systems in the list.

Begin Loop

1) Look for available system number in first system list in the same row as the random number. If system number is found, use it and blank out entry in first list. If a blank is found at that row number, then try to find system number in second list at same row number. If found, then use it and blank out entry in second list. If not found in second list, then generate another random number and go back to first list and look for new system.

2) Select the system in the same row as the random number.

3) Create list of KAs for Tier, ROGroup, and randomly selected system number.

4) Generate a random number between 1 and number of KAs in KA list.

5) Pick KA from KA list at the row designated by the random number.

6) Check to see if KA is in master list of KAs already selected. If it is in master list, then select another random number and select KA at that row number. If not selected, then add to master KA list.

7) Add KA To RO outline.

Loop Back (until number of required KAs have been selected for specific tier, group, and category)

Go back to top of list until all tiers, groups, and categories have been cycled through.

36 Random Selection: SRO Exam OBDI 202 - ILE Process

25 SRO Only KAs are first selected for the following categories:

Tier 1: A2 and G (10 KAs are selected)

Tier 2 A2, G, and Fuel Handling KAs (8 KAs are selected)

Tier 3 (7 KAs are selected, at least one for each category)

System lists are generated based upon the following criteria:

Tier, SROGroup, Category, SROOnly = True in tblCFRs Then 25 KAs are selected based upon systems selected with the following criteria:

Tier, SROGroup, Category Select Tier, Group, and Category to add KAs to.

Generate Random Number Between 1 and number of systems in the list.

Begin Loop

1. Look for available system number in first system list in the same row as the random number. If system number is found, use it and blank out entry in first list. If a blank is found at that row number, then try to find system number in second list at same row number. If found, then use it and blank out entry in second list. If not found in second list, then generate another random number and go back to first list and look for new system.

2. Select the system in the same row as the random number.

3. Create list of KAs for Tier, SROGroup, and randomly selected system number.

4. Generate a random number between 1 and number of KAs in KA list.

5. Pick KA from KA list at the row designated by the random number.

6. Check to see if KA is in master list of KAs already selected. If it is in master list, then select another random number and select KA at that row number. If not selected, then add to master KA list.

7.Add KA To SRO outline.

Loop Back (until number of required KAs have been selected for specific tier, group, and category)

Go back to top of list until all tiers, groups, and categories have been cycled through. OBDI 202 - ILE Process
