What do I expect students to know about drywall installation?

Drywall Expectations:  
1.  Identifies the correct use of tools used in the drywall trade; knife, hammer, saw, roto zip, drywall square, sander, sawhorse, panel lifter, corner bead, staple gun, drywall drill, drywall lifter, drywall saw, keyhole saw, and circle cutter.
2.  Works safely watching out for hidden hazards; keeps a clean area, removes scraps promptly, does not over reach on a ladder, takes time to build scaffolds safely when necessary, does not take any undo risks, asks for help with large panels, remains attentive to the process until the drywall is secure, wears safety glasses when nailing over head, keeps tools sharp and safe without damage to them.
3.  Determines the proper type of drywall to be used; water board, quarter inch, half inch, or five eighths.
4.  Determines the best use of the material; chooses the right length for the minimal amount of waste, looks for areas where the cut off may be used before cutting the first panel.
5.  Marks the studs on the wall for easy identification of the trusses. 

6.  Measures the center of the boxes and light fixtures and keeps a record so no box is covered up.
7.  Determines whether long edges will be parallel to or perpendicular with the studs; carefully makes measurements, taking a reading for each side of the panel.
8.  Accurately cuts panels using a knife; snaps panel by pressing down on the over hang; smooths cut if necessary and always cuts on the finished side.
9.  Does not force drywall; taking care to not damage the corners.
10.  Determines proper type of fastener; draws panels tight against studs; nails panel straight and true; "dimples " the nail head without breaking the surface.

Drywall Fastener Expectations:
1.  Understands the various drywall fastening techniques; nailing, screwing, glueing,
2.  Knows how to use the drywall fastening tools; drywall hammer, clutch driven drywall screw gun (knows how to adjust the depth of the bit), battery powered quarter inch drill and phillips screw driver.
3.  Chooses the proper fastener; one and one quarter inch coated nail, annular ring nail, or phillips head screw.
4.  Cuts holes for lights, switches and outlets after perimeter nailing and before installing the screws to avoid improper attachment.
5.  Marks the placement for the nails before installing the panel to assure the spacing is correct; twelve inches OC on the ceiling and sixteen inches OC for the walls, and eight inches on the end seams.

6.  After gaining experience the measuring of each nail or screw can be estimated as long as it is within a two inch margin of error.
7.  Understands the nail and screw attachment; drives nails/screws straight, dimples the nail head without breaking the surface, not too deep, not too shallow, not too close to the edge, does not pulverize the drywall, and immediately removes nails/screws that are not driven correctly.
8.  Understands that studs are sixteen inches on center and trusses are twenty four inches on center.
9.  Does not nail door or window edges excessively because additional nails will be added during other sequences of construction.
