Training to become an Interdimensional Marshal is an intensive and difficult process that can span many years. The ability to become a marshal is open to any and all races, creeds, and faiths, as long as the cadet in question is able to adhere and enforce Marshalship conduct, regulation and law. Training is available to subjects of all levels of education; the length of time as a cadet is highly variable depending upon the cadet. Highly trained persons coming into the Marshalship (often from other organizations) face a minimum of two standard years of training. Many join the Marshalship as teenagers or mid-level education graduates, these cadets generally remain in training for four years. Those younger or with lower levels of education have varied time in training, often depending on the cadet's diligence. Upon enrolling with the Marshalship, cadets are given a series of tests to establish what subjects they will require further training on.

     There are three stages of Marshalship training; Basic Training, Mid-Training Qualifications and Advanced Training. Each stage is worked through at a pace specific to each cadet, with no forced length of time per student. Courses in all stages vary dramatically, as Marshals are required to be knowledgeable and trained for many possible situations on many possible worlds.

     There are many required courses in Basic Training cadet must take to graduate, such as: Marshalship History, Marshalship Policy and Regulations, Dimensional Mathematics, Close Quarters Combat, Basic and Advanced Firearms, Dimensional Theory, Basic Piloting, Applied Diplomacy, Combat Focus, Basic Investigation, Magical Theory, Practice and Defense, and Covert Operations. 

     After Basic Training, Marshals chose a field to specialize in, called their Focus. To demonstrate that a cadet is ready to move onto the second stage of training and chose their Focus, cadets' classes turn into a series of qualifying courses called Mid-Training Qualifications. These intense courses serve as weekly micro-exams, testing a cadet's mastery of textbook basics, understanding of field concepts, technical know-how, combat readiness, and other topics covered in-depth during Basic Training.

     Once passing the Mid-Training Qualifications, which generally take approximately six months, cadets chose their Focus topic and move into Advanced Training. This is often the time where many cadets decide if they wish to become technical, instructor or field marshals. Some Focus fields are: Mech Operations, Spacecraft Operations,  Diplomacy and Negotiations, Mech Design and Engineering, Spacecraft Design and Engineering, Heavy Combat Efficiency, Magitek Operations and Engineering, Specialized Covert Ops, Dimensional Navigations, and Magical Instruction. Any subject involving magic has been recently added to the training regimen within the last 5-10 years and the Marshalship has few magical specialists at this time, though they are encouraging more.

     Training is accomplished by various methods. Basic facts and subjects needing mundane memorization are often broadcast via delta-wave broadcast during sleep hours. Engineering classes are held within the authentic dry-dock facility build in the Academy zone of Gatekeeper. Combat training is done in many facilities, including on Academy holodecks and on planet-side operations.

     With the current ongoing Void Conflict, many cadets have been assigned to the field for on-the-job training, this is a fairly recent development brought on by the strain of resources and manpower the Marshalship is currently suffering. To continue cadets' classroom education, many courses are administered via correspondence. These classes are given as multimedia presentations and simulation chamber exercises, most commonly, as well as field and ship-side demonstrations. Other training is administered by field assigned Marshals and consultants who have been Marshalship certified to train in their particular fields.

     Marshalship Certification is not a difficult status to achieve, as many non-Marshal 'consultants' with places on Marshalship vessels and in Marshalship crews are heavily encouraged to seek such certification. Certification usually only requires a few weeks worth of basic course-study and testing; rarely longer than a month. Consultants with certification who are actively teaching cadets and other consultants receive a pay increase.
