1. Have the Advanced Beginners Swimming Honor.
For tips and instruction see [[AY Honors/Swimming - Advanced Beginner|]].
2. Demonstrate properly the following dives:*
It is exceedingly difficult to write out how to perform dives, so watch these or similar videos or find a good diving instructor.
a. Swan

c. Half twist

3. Demonstrate properly two of the following dives:*
Note: * Basis of Judging: Attention position for running dives; attention position on end of board for standing dives based on the following:
- a. Approach
- b. Spring
- c. Way body is carried through the air (layout, tuck, or pike)
- d. Entry into water
a. Half twist

e. Back jackknife
f. Half gainer (tuck, pike, or layout)

4. State the safety depths of water under a one-meter board, a three-meter board, and a tower. How far should the board project over the pool? What boards are recommended?
Springboards are usually located either 1.0 or 3.0 metres (3 ft 3 in or 9 ft 10 in) above the water surface. It is very seldom that one is mounted at a height other than these two standard heights.
| Board Height | Pool Depth | Projection (NCAA) & |
|---|---|---|
| One meter | 2.5 meters | 1.5 meters |
| Three meter | 5 meters | 1.5 meters |
| A tower | 8 meters | 1.5 meters |
Historically springboards were made of wood. Modern springboards (since about 1960) are made out of a single-piece extrusion of aircraft-grade aluminum. The Maxiflex Model B, the board used in all major competitive diving events, is made out of such aluminum, and is heat treated for a yield strength of 50,000 psi. The slip-resistant surface of the board is created using an epoxy resin, finished with a laminate of flint silica and alumina in between the top coats of resin. This thermal-cured resin is aqua-colored to match the water of a clean pool.
