Most Kukkiwon schools will use the Poomse Taegeuk whereas a few schools will use the Poomse Palgwe. Very few teach both. In my opinion you produce a much more well rounded student if they know both. Palgwe Poomse were used from 1967 to 1971. Taegeuk Poomse have been in use from 1971 to the present time. Kukkiwon states that Palgwe Poomse have been eliminated. The official forms for Kukki-Taekwondo, as mandated by the Kukkiwon (World Taekwondo Headquarters), are the Taegeuk Poomse.
Taekwondo rank
structure is built in what are called Geup, or Gup. There are 10
Gups 10 being the beginning or White-Belt and the 1st Gup Red with
Black stripe. There are 10 Gups and only 8 forms, that's because the
first two white belts are for learning Taekwondo basics. The white
belts learn basic forms Ki Cho Ill Boo; Ki Cho Ee Boo; and Ki Cho
Sam Boo.
Belts under Black Belt are referred to as
"Colored-Belts".
Once at Black Belt there are degrees or Dan’s. First degree Black Belt is a first Dan, etc.

Koryo
Koryo, or Goryeo, is the name of an old Korean Dynasty. The
people from the Goryeo defeated the Mongolian aggressors. It is
intended that their spirit is reflected in the movements of the
Poomse Koryo. Each movement of this Poomse represents the strength
and energy needed to control the Mongols.
Keumgang
Keumgang means "diamond," symbolizing hardness. Keumgang is also
the name of the most beautiful mountain in Korea, as well as the
Keumgang warrior, named by Buddha. Thus, the themes of hardness,
beauty, and pondering permeate this Poomse.
Taebaek
The legendary Dangun founded a nation in Taebaek, near Korea's
biggest mountain Baekdoo. Baekdoo is a known symbol for Korea. The
definition of the word taebaek is literally "lightness". Every
movement in this Poomse is intended to be not only be exact and
fast, but with determination and hardness resembling the mountain
Baekdoo, the origin of the nation of Korea.
Pyongwon
The definition of Pyongwon is "stretch, vast plain." The name
carries with it a connotation of being large and majestic.
Sipjin
Sipjin stands for ten symbols of longevity, which are Sun, Moon,
Mountain, Water, Stone, Pine tree, Herb of eternal youth, Turtle,
Deer, and Crane. This Poomse represents the endless development and
growth by the basic idea of the ten symbols of longevity and the
decimal system.
Jitae
This Poomse is derived from the meaning of the earth. All things
evolve from and return to the earth, the earth is the beginning and
the end of life, as reelected through the Yin and Yang.
Cheonkwon
Cheonkwon literally means 'sky'. In the Poomse, the sky
symbolizes the ruler of the universe. According to belief, it is
mysterious, infinite and profound. The motions of Cheonkwon are full
of piety, vitality and reverence.
Hansoo
This Poomse is derived from the fluidity of water which easily
adapts within nature. The symbol of the water repeats itself many
times throughout all Poomse, hyeongs, and in martial arts in
general.
Ilyo
The state of spiritual cultivation in Buddhism is called 'Ilyo'
which means 'oneness'. In Ilyo, body and mind, spirit and substance,
"I" and "you" are unified. The ultimate ideal of the martial art and
Poomse can be found in this state. It is a discipline in which every
movement is concentrated on leaving all materialistics thoughts,
obsessions and external influences behind.
