Training and Development Specialists pay in Delaware and Mississippi
The May 2025 BLS OEWS median for Training and Development Specialists is $88,570 per year in Delaware. It is $53,680 per year in Mississippi. Delaware is 65.0% above Mississippi on the published median.
Both rows use SOC 13-1151 and the same annual wage metric. Median means the middle of each area's published wage spread. It is not one worker's pay. The larger median is not proof that one place gives a better job or a better result. It is one wage fact from one source period.
BLS lists 1,590 wage and salary jobs in Delaware and 2,820 in Mississippi. Those are survey job counts, not open posts. Read pay, job scale, local share, and price level as separate facts before you make a choice.
