The Knesset that served for the longest term was the third Knesset, which lasted for four years and four months. The fourth Knesset holds the record for the shortest term of only one year and nine months. On average, Knesset elections are held every three and a half years.
Member of Knesset Joseph Shprinzak served as Speaker of the Knesset for 10 years, the longest term of any speaker. Shprinzak served as the speaker from the day the Knesset was founded until his passing in the middle of the third Knesset. His replacement, MK Nahum Nir, served for only eight months, the shortest term as Speaker of the Knesset. MK Nir was the only speaker who was elected from the Ahdut Ha`avoda – Poalei Zion party, which was not a part of the coalition.
In the 15th Knesset, MK Avraham Burg from One Israel was elected to the position. During the term of that Knesset, special elections were held for the position of Prime Minister, and Ariel Sharon from the Likud party was elected.
Nahum Nir was the oldest MK elected at 75 years of age. The youngest Speaker was Avraham Burg at 45.
Of the 16 MKs who served as Speaker of the Knesset, there has only been one woman, MK Dalia Itzik, Speaker of the 17th Knesset. MK Yitzhak Shamir was the only Speaker of the Knesset who was later elected as Prime Minister, and Reuven Rivlin was the only one who was elected to the role of President.
Seven speakers were elected from the Likud party, seven from Labor, one from Kadima and one from Ha`avoda – Poalei Zion.

In the 8th, 10th, 13th the number of factions that were elected stood at 10, the lowest amount ever.
