Hi Nesh,

To do this you need a VisualForce page and a controller extension.

The controller extension, let's call it "CreateTrainingSurveys.cls", will contain your code.  I've optimized the code a bit to move the record type query out of the loop and to make the code easier to get code coverage:

public class CreateTrainingSurveys
{
    public CreateTrainingSurveys( ApexPages.StandardController controller ) {}

    public void createSurveys()
    {
        Set<String> set_SurveyTypes = new Set<String>{ 'Day1', 'Day3', 'Day5', 'Dropped' };

        Map<String,Id> map_RecordTypeIDs = new Map<String,Id>();

        for ( RecordType recordType :
            [   SELECT  Id
                FROM    RecordType
                WHERE   (   sObjectType = 'Training_Survey__c'
                        AND Name IN :set_SurveyTypes
                        )
            ]
            )
        {
            map_RecordTypeIDs.put( recordType.Name, recordType.Id );
        }

        List<Training_Survey__c> list_TrainingSurveysToCreate = new List<Training_Survey__c>();

        for ( Training__c training :
            [   SELECT  Day1SurveyFlag__c, Day3SurveyFlag__c, Day5SurveyFlag__c
                FROM    Training__c
                WHERE   (   Day1SurveyFlag__c = true
                        OR  Day3SurveyFlag__c = true
                        OR  Day5SurveyFlag__c = true
                        )
            ]
            )
        {
            String surveyType   = training.Day1SurveyFlag__c    ?   'Day1'
                                : training.Day3SurveyFlag__c    ?   'Day3'
                                : training.Day5SurveyFlag__c    ?   'Day5'
                                :                                   'Dropped';

            list_TrainingSurveysToCreate.add
            (   new Training_Survey__c
                (   Training__c     = training.Id,
                    Survey_Type__c  = surveyType,
                    RecordTypeId    = map_RecordTypeIDs.get( surveyType )
                )
            );
        }
        insert list_TrainingSurveysToCreate;
    }
}

The VF page, let's call it "CreateTrainingSurveys.page", should be something like this:

<apex:page standardController="Training__c" extensions="CreateTrainingSurveys" action="{!createSurveys}">
<script>
    window.history.back();
</script>
</apex:page>

That's all you need.  The button will launch this page, which will display for a moment and then return to the page that you came from.  If you want, you could put some content on the page, like "Creating Training Surveys - Please Wait..."

Note that you must use the standard controller in order for the page to be available as a list view VF button for the object.

Then, you need to go to Setup | Create | Objects | Training__c and create your custom list view button.

Finally, add the custom button to the appropriate layout.

If this helps, please mark it as a solution, and give kudos (click on the star) if you think I deserve them. Thanks!
