When Filipino women started to join the male-dominatedPhilippine National Police (PNP), they were only given assignments that administrative in nature and jobs that can be classified and described as "desk duties". Within the following thirty years - years after the establishment of the PNP in the early period of the 1990s, female Filipino police officers had been able to participate in other police activities and functions, including risky PNP operations. They have also became commanders in the field of police work. Among the Filipino policewomen who excelled in the PNP were Lina Sarmiento and Lorlie Arroyo.
In 2012, Sarmiento and Arroyo were the only two "female generals" in the Philippine National Police. They were both Chief Superintendents, with Sarmiento being the head of the Police Security and Protection Group (PSPG), while Arroyo was the head of the Crime Laboratory of the Philippine National Police. Arroyo's rank was equivalent to the rank of a brigadier general in the military. In June 2012, Sarmiento was promoted to become the "first two-star female general" of the Philippine National Police and the "first female general to be named in the Directorial Staff of the PNP" since the inception of the Philippine National Police.
As of June 2012, there were 11,000 Filipino policewomen within the Philippine National Police, an organization that at the time has a total of 143,000 police officers.
