Why should it be difficult to get a seo1 CEP? If an officer with aspirations is denied even SEO1 CEP, then they will not have any advancement prospects at all. Some teachers are happy with that because their goals are very clear: just to be a happy ordinary teacher all the way. But many teachers also have aspirations, and many teachers can be trained into good leaders if given the right opportunities and a nurturing environment.

The door is only closed on teachers who show, from very early in their career, that they have no potential whatsoever to be trained into a leader. This really only applies to the poorest performers.
