what are the guides to follow when marking fine arts practical? e.g 1. originality, what are the rest?

Are you not a graduate of arts? If no you shouldnt be marking art papers pls.

i have a reason for asking. no one is a custodian of knowledge. i want to know more because it varies from one place to the other

it depends on the kind of art you're marking. is it a still life or imaginative drawing? is it a painting? print? sculpture? or whatever kind of art we have out there. as a fine teacher, you ought to know how to grade the students' performance.

I have my first degree in fine arts, reason why I said so. Art works are scored by perfection, the more perfection you have against others youre peered with the more score you get. All arts practicals are scored based on the standard of creativity and perfection in it, though the issue of topic in paintings are relevant. Your art work should communicate and depict the topic you give to it otherwise you loose point. In ceramics for instance the weight of the work shld be as light as possible, the clay must be well sifted to give a smooth body work of art at finish level and of course the design you inscribe or emboss or paint on it also score marks as well as the shape perfection.
In pencil/charcoal/pastel drawings your strokes and blends makes your score and of course the effects of light and proper direction of the rays and shadows where such exist. Good representation of figures ure trying to depict even where distortion is an adopted style the figure shld still be apparent.
In sculpture, scores are similar to ceramics except that the stamina given to the figure and the durability of the finished work becomes relevant. Note u dnt always need a smooth finishing on sculpture as usually relevant in ceramics. But most of all the use of curves, flexibility, rigidity and how you were able to effectively use the material (medium) to attain your desired expression is the secret in sculpture.
Textile is entirely in its own world, cos it goes beyond the creativity in it, , it goes all the way to examining the marketable aspect of the design, the acceptance of the colour used as combined and figured. A good textile design is scored first by the colour combination, two by the motiff and three by the presentation and of course the consumer acceptability would be in focus because its more of an industrial art unlike painting.
Graphics, photography etc also have their varied scoring targets. BUT BASICALLY, WORKS OF ART ARE SCORED BY THE BEAUTY IT RADIATES, THE PERFECTION ACHIEVED AND THE CREATIVITY BEHIND THE APPLICATION OF THE MEDIUM USED.

I WAS AN EXCELLENT STUDENT OF ART, I KNOW ALL THE TRICKS TO WIN THE LECTURERS SCORE BEING THE FIRST TO SCORE "A" IN PAINTING IN THE HISTORY OF MY SCHOOL. no bi mouth o!

some group of lecturers criticized some of my gradings that is why i asked. they want me to pass some female students despite their poor performances in sculpture. thanks 4 ur contributions.
