Clear Creek Independent School District (CCISD) is a school district based in League City, Texas, United States. The district serves most of the Clear Lake Area and some other neighboring parts of the Houston metropolitan area. CCISD is the 29th largest school district in Texas, spanning 103 square miles and serving over 41,000 students. The district operates 45 distinct campuses, consisting of 5 comprehensive high schools, 3 alternative high schools, 10 intermediate schools, and 27 elementary schools.^[2] The Superintendent of Schools is Karen Engle.

Clear Creek ISD currently operates two football stadiums, Veterans Memorial Stadium and Challenger Columbia Stadium, both of which serve all five of the district's 6A high schools.

Clear Creek ISD was formed in 1948 when the districts of Kemah, League City, Seabrook, and Webster were consolidated, deriving its name from nearby Clear Creek, which forms Clear Lake, one of the few natural lakes in Texas. CCISD continued operating Webster High School until Clear Creek High School opened in 1956. The district opened Clear Lake High School in 1972, Clear Brook High School in 1988, Clear Springs High School in 2008, and Clear Falls High School in 2010.^[3]

In the 2000s, rising real estate costs in Galveston forced many families to move to other areas, including League City. This meant an influx of children out of Galveston ISD and into other school districts like Clear Creek ISD.^[4]

On May 11, 2013 the district was successful in a vote securing $367 million to "...rebuild or improve 40+ year old schools; address student safety, security systems, repairs and enrollment growth; construct or expand co-curricular and extracurricular facilities for growth in programs; and improve wireless infrastructure and access to technology for 21st century learning."^[5]

On May 6, 2017 the district was successful in a vote to approve a bond with largely the same purpose stated in 2013 "...to build new or rebuild schools, replace portables with permanent additions, renovate aging schools to bring them up to today’s learning standards, improve school and bus safety through the purchase of surveillance equipment and buses."^[6] This second bond in 2017 for $487 million resulted in a 4-year total of US$854 million of funding over and above that allocated by the state for this purpose.

CCISD is the 29th largest school district in Texas. The total enrollment for the district is currently 42,008 students. According to the last CCISD reported actual financials (2017-2018), the annual per student cost is over $12,000.

Eric Williams became CCISD superintendent in February 2021. By December a group of parents accused him of promoting "critical race theory" in K-12 schools.^[7] Williams had stated he would not promote CRT and he would not close campuses with incidents of COVID-19.^[8] Williams resigned in July 2022.^[9]
