How has the NJATC grown in terms of membership?

The New Jersey Apprenticeship and Training Committee (NJATC) has seen a significant increase in membership, which reflects the growing demand for skilled electricians and the commitment to workforce development within the industry. The correct choice indicates a notable increase, specifically mentioning that the membership has doubled. This growth is indicative of the program's success in attracting new apprentices and emphasizing the importance of training and education in the electrical field.

While considering the context of the other options, it's clear that a doubling of membership shows positive trends in recruitment and industry needs without overstating the growth that might suggest even larger, less plausible increases, such as tripling or quadrupling. The concept of "remaining the same" contradicts the trends observed in skilled trades, especially amidst advancements in technology and energy efficiency that often stimulate the need for more trained professionals. Thus, the choice that membership has doubled accurately captures the growth and momentum of the NJATC in training new electricians.
