None of them are qualified, but. If you are qualified, you will get a five-level (primary) certificate (valid for one to three years), a four-level certificate (intermediate) after one year, a three-level certificate (advanced) after three years, and then a two-level (technician, basically at least the stationmaster of the airport scanner) and a one-level (new this year).
My exam fee is 229 (different from place to place), depending on where you go (generally 6000 to 8000).
Airport security inspection is a decent job for outsiders, but only you know the pain and suffering.
Airport security is different from aviation security. Airline security inspection enjoys the high-quality treatment of airlines, and airport security inspection enjoys the treatment of airports, so there are grades.
Even so, the welfare of the airport is better than that of most units, and there are various subsidies, such as meal supplement, car supplement and telephone subsidy. There are also gifts for Chinese New Year holidays, such as moon cakes for Mid-Autumn Festival, zongzi for Dragon Boat Festival, daily necessities for Chinese New Year, and even cosmetics for Women's Day on March 8th. There is a half-year prize in the middle of the year, a year-end bonus at the end of the year, and two paid rest and recuperation holidays every year.
