TLDR: core = beginner + intermediate
A proficiency level of a training is commonly categorized as beginner, intermediate, advanced. Such division surely does apply in other fields of education, however in case of Adobe applications, we find it impractical, or even confusing.
The reason is very steep learning curve at the beginning of studying Adobe applications. Novices need to invest considerably large amount of time and effort to even begin operating on their own.
The concept of “steep learning curve” may be illustrated with an example of training to pilot an aircraft. A set of skills is needed there: knowledge of an airplane construction, geography, a meteorology, a structure of an atmosphere, etc). Only merging those indispensable competences combines into flying a plane. It’s a necessity to master them altogether – You cannot take off a plane “partially”, “a little bit”.
In our experience, it is more profitable for participants to deliver the “Illustrator core” material as a whole and not to artificially divide it into “beginner” and “intermediate”.
Before mentioned commonly used categorization (beginner – intermediate – advanced) might be compared to our offer in such a manner: in case of Illustrator, the “beginner” level does not exist at all, and our “Illustrator core” is adequate to “solid intermediate plus”.
The “core” in the training’s name refers to a hub, an crucial essence of tools, skills and procedures which must be mastered, regardless of the specific nature of performed tasks.
After participating in the “Illustrator core” training, at least 6 months are required for a new knowledge to settle in. After mastering the material presented in the “Illustrator core” training and having some real world practice, You might want to upgrade Your knowledge by taking the “Illustrator advance↑” training.
The universal knowledge of the “Illustrator core“ may be expanded in many directions. As Oxygrafia specializes in area between artwork creation and printing, allow us to draw Your attention to the training “Prepress for designers”, focusing on graphics print preparation and cooperation with a printing house.
