Run one workshop across three crafts
Kept sculpture, painting, and goldsmithing going side by side in a single bottega, a high-demand shop that took bronzes, altarpieces, portraits, and metalwork at once.
Why it matters · The crafts fed each other. A sculptor's grip on form went into the painting, and the goldsmith's precision went into the finish. A painter who trained there thought across media instead of down one narrow track, which is a large part of what produced Leonardo.
Documented range of the bottega: bronzes, altarpieces, portraits, and goldsmith work made side by side (Vasari, Le vite; Florentine records).
Put drawing before paint, without exception
Made disegno the foundation of an apprentice's whole education, moving from copying the master to drawing casts and then life, years before a brush was allowed.
Why it matters · Drawing here is not outline. It is the thinking tool for form, perspective, and composition. Holding a student off paint until the drawing held meant everything painted later sat on a structure that was already sound, which is the Florentine argument for disegno in one habit.

Draw drapery hardened over a model
Arranged cloth dipped in plaster or liquid clay over a clay model or mannequin, let it set, then had students draw the fixed folds with sustained patience.
Why it matters · Fabric moves and the light on it never sits still. Freezing the drapery turned it into a small sculpture a student could study for as long as it took, which teaches the eye to read light on a three-dimensional form before it has to catch one that shifts.

Hand real commissions to advanced pupils
Gave assistants and senior apprentices significant parts of major commissions, keeping the design and the final touches for himself.
Why it matters · It was a business model and a training method at once. An apprentice learned by working on real, high-stakes panels under the master's eye rather than on exercises. The famous case is the young Leonardo painting an angel into Verrocchio's Baptism of Christ.

Build figures on perspective and geometry
Worked from a rigorous, measured grasp of perspective and geometry, a discipline Vasari tied to "infinite study" rather than easy natural facility.
Why it matters · Vasari found Verrocchio's manner a little hard and crude, and traced it to how hard he worked for it. That constructed rigor is what let figures and spaces hold together convincingly, and it is the seed of Leonardo's later insistence that practice rest on theory and perspective.
