Hi Vishal!

I would create a IInitializableModule and listen to DataFactory event PublishedContent. It could look something like this:

[EPiServer.Framework.InitializableModule]
public class DataFactorySubscriber : EPiServer.Framework.IInitializableModule
{
    public void Initialize(EPiServer.Framework.Initialization.InitializationEngine context)
    {
        context.InitComplete += InitComplete;
    }

    private static void InitComplete(object sender, EventArgs e)
    {
        DataFactory.Instance.PublishedContent += PublishedContent;
    }

    private static void PublishedContent(object sender, ContentEventArgs e)
    {
        var educationPage = e.Content as Education;

        if (educationPage != null)
        {
            CreateVariantPage("fulltime", e.ContentLink);
            CreateVariantPage("parttime", e.ContentLink);
            CreateVariantPage("dual", e.ContentLink);
        }
    }

    private void CreateVariantPage(string pageName, ContentReference parentLink) 
    {
        bool alreadyExists = DataFactory.Instance.GetChildren<EducationVariant>(parentLink).Count(child => child.Name.Equals(pageName, StringComparison.InvariantCultureIgnoreCase)) > 0;

        if (alreadyExists)
        {
            return;
        }

        var variant = DataFactory.Instance.GetDefault<EducationVariant>(parentLink);

        variant.PageName = pageName;

        DataFactory.Instance.Save(variant, SaveAction.Publish, AccessLevel.NoAccess);
    }

    public void Uninitialize(EPiServer.Framework.Initialization.InitializationEngine context)
    {
        context.InitComplete -= InitComplete;
        DataFactory.Instance.PublishedContent -= PublishedContent;
    }

    public void Preload(string[] parameters)
    {
    }
}

Hope that helps!

Thanks  alot for this mattias... This is what I needed... 

Great, just what I was looing for!
