This is a Demand OccupationA Demand Occupation is defined as follows.

The hierarchy for qualification is the Regional Demand
(the occupation had a entry wage equal to or greater
than 90% of the Economic Development Region (EDR) negotiated
wage as an average of all LWIA’s in the EDR AND at
least 25 annual average job openings in the EDR);
State Wide (the occupation qualified for at least
5 of the Regional Demands and thus was added to all
ten EDR lists); Career Cluster (the occupation is
listed on at least one of the six career clusters
Illinois has identified as priority [data is available
under the career clusters on the The National
Association of State Directors of Career Technical
Education Consortium website at ]), and Regional

Rock splitters use jackhammers and other tools to cut pieces of rock away from larger masses.

Rock splitters inspect large masses of rock in rock quarries. They determine the pattern of the grain, because this pattern shows how the rock will split when cut. Splitters measure rocks and use chalk lines to outline the shape of the rock to be cut. They chisel grooves into the outline. Rock splitters use sledgehammers to drive wedges and shims into the grooves. Sometimes they use jackhammers to drill holes into the rocks.

Once they have removed large pieces of stone, rock splitters may do additional work on them. They may smooth the edges or cut slabs of stone into sheets that will be used for floors or counters.
