Performance Narrative [Text Block]	The following bar chart and table beneath it provide some indication of the risks of investing in the Fund. The bar chart shows the Fund’s performance from year to year. The table shows how the Fund’s average annual returns for the indicated periods compare with those of an appropriate broad-based securities market index and more narrowly based indices. The bar chart and table include the effects of Fund expenses and assume that you sold your shares at the end of the period. The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as individual retirement accounts.The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future.Updated performance information is available on the Fund’s website at thriventfunds.com or by calling 800-847-4836. The Fund compares its performance to the Russell 3000® Index, an appropriate broad-based securities market index that represents the overall domestic equity market in which the Fund may invest. The Fund also compares its performance to the Russell Midcap® Growth Index and S&P MidCap 400® Growth Index, which more closely reflect the market segments in which the Fund invests. The index descriptions appear in the "Index Descriptions" section of the prospectus.
