Peñalara has been working on teacher and resource planning for over 20 years with notable success, more than 6,900 customers and present in more than 25 countries. The main characteristic of GHC is its calculation engine, capable of automatically and satisfactorily resolving any problem in planning teachers, classrooms, subjects, class units, etc. It does not only find a solution if there is one, but also optimises it by trying to fulfil the conditions that have been introduced into the software. GHC is easy to use, being able to watch from its web page a great amount of video tutorials that describe all the functionality of the software, being an interesting learning tool. As a success story, all the secondary schools in the Community of Madrid have been users of Peñalara for more than 8 years. GHC has managed to make the hard work of drawing up timetables in highly complex academic institutions much easier. As a new feature, the latest version of GHC incorporates interesting web services that allow for better interaction between the software and the user.
